Got her back from tuning!!!

[clipsit]

So I told some people I would post when I got my car back from tuning... as far as my fuel setup and what not...so here are some rough numbers, until I can take some pics of the dyno sheets and show what it looks like and some proof. I have not looked at the settings yet...to write them down, just to make sure I have some back up settings just in case something happens to the SAFCII or you know whatever. So here are some numbers. It was done on Dynojet.

Fuel setup:
RC 550cc
SARD FPR
SAFCII
255fp

Made:
220.06 whp
231.53 ft-lbs

On pump gas:
Spiked to 15 psi b/c of Back pressure. Got to get the 3" cat back.
Holds at around 13 psi

Star stage 2 and all the goodies...Everything is listed in my profile. I still have to get pics posted. All of my pics are too big and I have to spend the time to crop them. Anyway I will also post pics of the dyno sheet asap and as soon as I can get a digital and post them. Thanks for looking guys I will hopefully turn up the boost here in a few months and tune her some more!!! The numbers seem kind of low...for 15 psi, but she definitely runs really well and maybe I was setting my goal to high, but she still idles like crap. I am happy w/ these numbers for now, but will eventually see how much I can run on pump gas and fine tune her. Maybe somewhere in the 16-19 psi range. Feel free to ask any Q's. Goes to show you can fine tune w/ the SAFC...just takes time and experience...someone elses experience that is ...seriously though...I am still learning. The fuel setup is almost like SBR's, but w/ afpr. Let me know what you guys think. Thanks for looking'.

Its about time Clipse...., car is real nice, can't wait to see some pics.

 

[clipsit]

Thanks Rand, much thanks man...you I probably wouldn't be here now at this point w/ out some of your wisdom and everyone else that I have gained knowledge from, on the forum. !!! I waited along time to be turboed and now she's tuned, but there is still work to be done. And I am glad I will be a witness of when Rand gets his monster up and running. And all those V8's will hear is... . Thanks Rand.

 

[XMasta19]

wow, I sure would have been hoping for more....but it's all good I guess, keep up the good work

 

[clipsit]

I know what you mean...I was expecting at least 250+ whp, but maybe that me was setting my expectations too high. I will see what the deal was and what can be done to squeeze some more numbers out of her. Just maybe more tuning....Thanks X.

 

[clipsit]

Anybody possibly know why my idle sucks A$@ still? It idles anywhere in between 1100--2000!!! That is outrageous!!! I have a CEL light still. It might just need to be reset b/c it was running rich before. I will check what the CEL is and post later what I find. It is still odd to me why I didn't make more power though? Any suggestions welcome? It was tuned by a really well known place in the area, so i don't think it was their tuning abilities, but it's just odd . Like I said before, I am glad w/ the numbers that I got, but they seem low for 13-15 psi...Don't they? Maybe the turbo? I hope to turn the boost up here soon though...like I said before. Thanks guys for the feedback.

 

[swarm]

Are you using stock 2gnt ECU with SAFCII?
Checked for boost/vacuum leaks?
What is your base fuel pressure set at?
Does it just idle surge between 1100-2000?


Seems like to me, it is a fuel problem. The car runs great other than idle?

 

[clipsit]

Yes to the first Q. Yeah.. the car runs awesome, especially getting it back from tuning. They set the fuel pressure, but I don't what it is, but they checked it witht their gauge. I might just need to go through and check all of the sensor and maybe my TB sensors and what not. It recently got bored out, and it wasn't a very good job, but I don't know if there is space in between the plate and the walls of the Tb if it would do that...I don't think so? The other thing is it is inconsistent. Sometimes it idles at around 1100 which is fine, but a little high. Other times I have to rev it to get it back down...and when it goes back down it comes right back up again. Also when I down shift or am coming to a stop it revs up to 3 grand and holds and then comes back to 2 grand and goes up and then it finally settles to wherever. Let me know what you guys think? Thanks.

Possible bad throttle position sensor, this sensor is located on the back of the throttle body, replace it and see if it fixes the issue. Sometimes the spring on the throttle body gets stuck as well. Also you should have a lot more power then that at 15lbs. I had that at 8lbs, What is your compression. What did they tune the car for Air To Fuel ratio wise?

 

[baxsom]

i hope this doesnt sound bad but you should be putting more power down at 13 psi
my 222whp was at 8psi

did they tell your your afr if its too rich that is stealing power

 

[XMasta19]

I also believe the numbers are low, but do you guys have built motors? If not, of course you'll be making more power with less boost due to the higher compression ratio.

 

[clipsit]

It just keeps on getting worse... the idle that is. It is surging now from 1 grand to 2 grand...Back and forth, back and forth. I think the problem is my IAC valve. I have a check engine light and the codes are P0505 and P1294 which I am pretty sure are related. Also what kind of turbo is everyone using? B/c I know that at 15 psi I should be making some sick HP, but I was told it was more the limits of my turbo charger that I was using? It's the t3/t4 turbo that comes in the star kit...so the numbers I have are right around what they say for the kit, but should definitely be higher!!! My compression is 8.8:1. My a2fr is right around 11.5 or so...so pretty good!!!. I don't know. I mean it runs and pulls great, but it's not necessarily the numbers that I want to flaunt, but I was thinking I would be disappointed if I didn't make around 250 to the wheels, which I think is realistic and I can still reach. Also certain engines, whether they be the same or not respond differently, but at 15 psi it certainly should be making bigger numbers. Thanks again for the feedback. I am by no means an expert...yet and I do know my stuff pretty well, but I really appreciate all of the feed back that I am getting so keep it coming dsmers!!!

Were these numbers before or after you were built? It looks like you both are built now, but what about your dyno numbers now? Let me know. And baxsom...you got that freakin portfueler!!! I got to get one of those.... Anyway, let me know guys. Thanks.

 

[BigRand]

You know rameses, I'd see if you can't get a dyno pull somewhere else to see if the numbers or the settings are the same. I got a guy in Olympia that has a dyno at his shop called horsepower connections. He probably wouldnt' charge very much for 2 pulls just to compare.

 

[selmerguy]

Hey dude I am glad you got tuned and I have an idea why your numbers are lower then you want. I dont think your fuel setup works too well. Your fpr is a 1:1 right:? If so the safc cant do all the work to tune those big 550s. Your idle fp should be around 35 psi to have a good idle with those big fuel dumpers. So the problem comes when you are at wot and hitting 13 psi you have a total of 48 psi which is not enough. I am sure the people tuning your car ran into this problem. The only way to fix this is to push up that idle fp.(why your idle sucks???) This also results in to much fuel in the low rpms. Which could be a reason for the low numbers. Can you post or pm me your dyno sheet?

Ok thats one thing the other is the safc itself. I had one and lots of other people have too. They are ok for "fine tuning" With the fuel setup you have the safc cant do it. And when you start to push that boost up alittle more and change more map sensor voltage(what the safc does) you are going to advance timing. This can be very bad for your health and your motor. BOOM!!!!!!

I dont know what your goal are but if you like the boost you are running get a sfmu and keep the safc. If you want more control and the ability to run some serious boost you have to go the ems route. Rand is doing the emanage thing. I dont know if he has it running right yet you might want to talk to him. I am going to msns and should have my stuff ready to install by the end of the month. Just waiting for it to be built. Good luck i cant type anymore.

You know ramses, I'd see if you can't get a dyno pull somewhere else to see if the numbers or the settings are the same. I got a guy in Olympia that has a dyno at his shop called horsepower connections. He probably wouldn't' charge very much for 2 pulls just to compare.

Hey Rand I might do that...just to see. We'll have to go up there maybe next weekend? Let me know or I will call you. Thanks man.

I don't know what your goals are but if you like the boost you are running get a sfmu and keep the safc.

Hey selmer...What exactly can I do w/ the sfmu? If I am tuned already...do I have to tune again w/ the sfmu? It does sound like a good deal, but I needed to get tuned and didn't have the time to get a sfmu and didn't really study up on it as much as I should've, but if it will help and you definitely think it will then I might try it. Does this mean I get rid of my FPR? Or does that mean I use it like I would w/ an fmu setup...w/ my FPR? Also, I am pretty sure the problem w/ my idle, is the IAC system, but I could be wrong, and it wouldn't be the 1st time, but I will keep you posted. I threw those CEL codes I listed above. I am getting those checked out here on Thursday to make sure the IAC motors are good and everything else. Anyway, let me know...And I also don't want to type anymore today so I think I am out. Thanks for the info and the suggestions guys. And yes I keep in touch with Rand, we live close to each other...it's kind of nice having another 420A turbo around who knows a thing or two about the business of a 420Aer. I almost forgot...I am still working on getting that dyno sheet up here soon..sorry guys. Until tomorrow...

 

[BigRand]

His idle problem is occured before he got tuned, but I bet it has a direct corrilation to his low numbers.

I'm so close to getting this emange thing to work, but I'm only base line tuning the 370cc injectors I have, I'll get a dyno pull done to see where I'm at, I want to save the real dyno tuning money for when I get bigger injectors that fit. (making 4g63 RC injectors fit on my custom fuel rail is proving to be a little more challenging)

If I get close to your numbers rameses, then will have to figure out the differences in our setup 's and find out whats robbing you of your horsepower if thats the case.

Hey do a qucik compression test on your car too.

 

[baxsom]

that was on a stage 2 kit

i havent put it on a dyno since the portfueler installation

i am still messing with the fuel tuning myself with my datalogger to try and get it in the ballpark before i take it to the dyno

the hahn map ran 9.5:1 ratio at 15psi when i first took it down the track

ugly

 

[selmerguy]

Hey selmer...What exactly can I do w/ the sfmu? If I am tuned already...do I have to tune again w/ the sfmu?

There are alot of people running 15 psi on between 440 and 550 injectors with only a street tune using the sfmu. So it all dependss on you and what you want to do. I dont think a 1:1 fpr and a safc can do well on you car togeather. I will give you an example. There are 40 people or so (or more) that i can think of running the sfmu and bigger injectors that i can think of. I have only seen one run bigger injectors and a 1:1 ratio fpr that was not running any sort of ems. His name on there is DSMZERO and i have not seen him post in along time. I know he is doing a rebuild and tring to make the fastest 420a out there but i dont know why he had to rebuild a allready buit motor(hint hint).

 

[clipsit]

So you are saying to get the SFMU and re-tune? And maybe hopefully I can fix my idle problem when I go get the IAC checked out. Thanks guys I will take all of this into consideration. I really appreciate the feedback and ideas. I'll post more later.

If i was you i would fo on and get megasquirt. You have the perfect fuel setup to run it. Depending on the price you pay for the sfmu you would be close to msns. I am getting mine for 510 shipped. If you dont want to go the route of megasquirt then get the sfmu and retune.

The megasquirt sounds like my best bet. I talked to Rand about it a few weeks ago, but I am unfamiliar w/ megasquirt. I know there is tons of info on it here and at the megasquirt website, but I recall you getting yours ordered w/ "all the bells and whistles" who are you getting yours through...if I may ask? Let me know who is the best to get it through. Thanks man I am willing to pay $510 for a set up that would compliment my setup. I just have to read up on it some more. If you can enlighten me on what the setup does and how it works? I know I should research it out, but since we are on the subject of it? Thanks I would appreciate it. Thanks alot Selmer and Rand. It will probably be a while before I pick up that megasquirt...research and parts or what ever it takes to order or piece together. You guys rock...and keep the feedback coming...I really appreciate it.

I will pm you and hook you up with him. This is not the place to sell stuff. Give me a min or so.

I definitely agree, if there is a bad idle, something is wrong. If something is wrong, the car will not perform at, or near it's full potential.

My dyno #'s are on stock injectors, 12:1 FMU street tuned with SAFCII and 6psi. All cars have different #'s...BUT we all know that you should be making more power, including yourself, don't get discouraged because you put a low number down, you know something is wrong, diagnose and fix it, then put down some higher #'s

 

[clipsit]

Depending on the price you pay for the sfmu you would be close to msns.

Thanks guys. I think I am going to go w/ msns. Thanks for the PM selmer. I wasn't trying to get the info on the thread, but I forgot to ask you to PM that info to me...My bad. Anyway, Selmer what did you mean when you said what I quoted up top? I guess I should research this, but does the msns include a SFMU? If it does, could I get the SFMU separate, re-tune and then do that in the meantime before I go msns? Or do you think I could be good until then, especially w/ having just idle problems. Just out of ignorance. I think I will keep the car how it is for now and when I get some money I can start on the msns. That is if I get the idle thing fixed, which hopefully is just the IAC system. I am crossing my fingers for that one. You guys know...it's all about having that $$$, which I only get once a month. I will probably put it off for a while, but make sure everything is still running ok. I mean the car performs awesome!!! But it all just doesn't make sense???? But I know it will all be good. Thanks again everyone, for the words of wisdom. I will be researching here soon. Also I know I am killing you guys w/ no dyno sheet up yet, but hopefully by this weekend.
