How successful was your tune?

[400hp93talon]

I see so much debating on this forum about tuning about you should do this and that and you should use this fuel over that fuel. If you actually know something about tuning and you tuned your own car PLEASE post the numbers your car made on what setup,fuel type,timing etc. Me myself Im still trying to learn so I want everyone to throw their .02 cents in here. I know it's hard not to argue about this kind of stuff as I've noticed but try to keep this thread postive and informative.....If you have an opinion PLEASE explain yourself but dont be disrespectful to each other.

I am tuning mine right now. It is still coming together, and it takes time. Time to not get frustrated, wait for responses on logs you posted cause your unsure of what to do next. If your using ecmlink I suggest watching the tutorials a few times, it helps out a lot. Right now I am trying to finish up my pump tune then I will be tuning for e85 using the switch mod for v3. Its not hard but I am not going to say it is at all easy. It will took a good learning curve and some time to learn it. If you get frustrated fast then it may not be for you yet. I havent got numbers yet, but when I am done with both tunes completely and am satisfied I am going to dyno then see if they can pull any more power out of and see how close I came to there numbers doing it myself. It is more for self satisfaction doing it that way more then anything. But the choice is up to you. Easiest is having someone do it of you, depending on who that someone is will depend on price. If you do it yourself it wont cost anything but time, and you gain knowledge.

Thats exactly the way I feel about being able to do anything myself.....Self satifaction and self confidence is the key factor there and it gives you the drive to try your best at everything even if you dont know 100% of everything you need to know you still give it your best shot. Also having a pro tune it after you to see how close you where is always a great idea. I'll probably wait until I get my girlfriend a 1g and tune on some stock 6 bolts before I do my own......I dont want my first mistake to be a 3000+ one haha and I can admit I'll mess up and it will take time to get it down but I'll give it 110% just to educate myself.

What's the difference, a mistake is a mistake and a very bad mistake that you do not bother fixing will destroy either motor. Just take your time and do the small things first so you get the hang of it.

It took me a while just doing idle and cruise tuning on Link before I felt "comfy" enough to do WOT tuning using the DA maps. Now I'm pushing 30+ PSI.

In DA are you jsut talking about timing maps or you doitn the open loop maps with A/F ratios?

 

[LiquidX]

Tune with both in The DA table.

 

[DSM_munky_man]

Hmmm, not to thread jack bout how and when do you adjust the A/F? if it is better you can pm me, cause i dont want to start a thread since I am not quite there yet and dont have logs to help, but to know how and what to do would be helpful now instead of waiting till i need it.

And to the OP i dont remember what you said what you would be tuning with, if you provided that it would help too that way we know what to help with, cause so far only experience with v3 and heard it is the easiest, compared to megasquirt or AEM.

 

[LiquidX]

For both of you, you will gain a lot of know-how by readig the wiki on ECMTuning, Inc.
Get your fuel to the desired ratio, keep an eye on the timing pull, adjust timing where needed.

The difference is my car has a fully built motor....and I feel more comfortable learning on a stock motor with some bolt ons. I would rather blow a stock 6 bolt with 150000 miles than a stroker thats brand spankin new just my opinion I have V3 for my 1g and I keep hearing how easy it is to learn....I've read up on the pointers on ecmlink.com and I'm starting to understand some of it.

My motor is built and that's what I learned on. The built motor should be more forgiving anyway.

The only time you are going to end up blowing up the motor is by running way too lean and not paying attention to "knock". You generally do not make huge jumps in numbers while tuning but rather small steps to see the kind of increase you are gaining.

Timing for instance, you could run 17* advance or 21* advance (examples). Going from 13* to 17* could yield you 20hp, however, going from 17* to 21* may only yield you an extra 5hp. You passed the optimum timing advance by going so much higher even if the motor is fine with it. That's a prime example of doing small steps at a time.

Same goes for fuel, start by leaning it out a little bit, keep an eye on your wideband and knock retardation (timing pull). Go a little leaner if everything is lining up well and there is no pull. Once you start getting pull either richen up the mixture a little or pull x* of timing.

It's very hard to blow up the motor if you go slow rather than just throwing 25psi at it, leaning out the map to 11.8 and giving 19* timing advance without logging.

 

[DSM_munky_man]

I did not find anything about the A/F map from DA in the wiki links. Not sure if I looked in the wrong spot, but I have been to everylink on there atleast 3 times since I got my v3.

 

[LiquidX]

Well basically for the DA changes when you do a pull and log it you will see what you are running for your values. If you are running 10.3 AFR and want to run a 11.5AFR, where you see the discrepancy you would go to your DA table, click on "track datalog" and the cell being used at that time will be highlighted.

Make your adjustment/s and log again. It seems confusing at first but it'll become simpler to understand. If you have ECMLink you should be able to access the forum as well and get the information there which I personally thought was in the wiki (sorry).

[DSM_munky_man]

So it is basically the same as adjusting time in the DA? So either you ahve a choice with knock, richen it up or pull timing? Which would be more benificial? Or do you adjust your A/F for other reasons as well? In my mind it all comes down to knock, if your tuning to the point of knock either add timing to getthere or lean it out. if you have knock then you pull timing or richen it up right? How do you know which is better?

P.S. and thanks for the last link too btw. I found the Ralliart maps and am interested in trying them out now.

 

[Gus@RRE]

Car: 2g w/6bolt
Fuel: 91 octane
Boost: ~24psi
timing: ~10*
power: 320.6 whp, 286.6 lb-ft/torque

This was the old setup i ran on my 2g for about 2 years. Its really hard to make decent power on shitty 91 pump gas, but that's the most i saw out of my old to4b 60 trim on 91 octane.

 

[JayRolla]

Car: 1g w/6bolt/2g pistons
Fuel: E85
Boost: 30psi E316G
Timing: ~22*
AFR: 12.0:1
power: Power is in my sig.

Its not that high because it was on a load bearing dyno. All dynos show different power levels. My car is estimated around 405whp in ecmlink which is closer to a dynojet power level. Turbo is gone now so I will never know what she made on a dynojet.

 

[dexterholland04]

LiquidX has a proven method as he described above. Get your fuel levels (AFRs) to where you want them to be and then add timing until you are using the highest safe value (with no knock). Make sure that you have your idle and cruise tuning done before you do your WOT pulls. Have your fuel trims in check and make sure that your airflow is dialed in (using the calculate airflow option after logging some idle/cruise logs). Of course there is a risk, as with anything we do...just be smart and don't heasitate to post logs or ask questions if you are unsure about anything.

 

[400hp93talon]

When you do start to do wot runs....Do you go up like a 1000rpms each run to gradually see what needs to be changed each time?

 

[Imback]

No.I personally make sure my idle and cruise is on point. Then from there i set it a little richer do a pull and start adjusting from there. There are many ways to tune a car this is just my personal preference.

Tuning is all gonna be in experience and general knowlege. And knowing the ins and outs of your software is gonna help tremendously. Ive been tuning hondas for the last 3 or 4 years. I tuned my civic on Crome which is essentialy free software and have tuned about 50 cars.

Civic made 721whp, 510tq on E85 at 24psi
Just started getting into the tuning side of things with my DSM but i have tuned a couple cars with ECM and DSMlink and as long as you have an idea, start off slow and just learn the basic functions of the software.
