* * Need Help Tunning 2g just got it On!!!!!!!

[BklynsDsmer]

Basic stuff that i have

50 trim turbo, 1050 injectors,safc2 ,afpr, 3 inch exhaust,255 pump, 28o, check profile,\



ok i just got my car to turn on, did a whole rebuilt , but it feels like crap, wont idle right, i tried messing with the safc and still feels like crap so i put the stock injectors back on and to find out it still feels like sh*t.

so i need some help on finding a fix for this.

i know this is the most important part to a dsm is the elctronics in it.

so far i know i have the eprom computer. so any help to get it to run atleast stock enough to drive till i can get a dsm or ecmlink.

You're not going to be able to dial in that large of injectors with a SAFC. If you keep the stock injectors in there make sure to zero out the Hi and Lo tables in your SAFC because you won't need any correction for the stock injectors.

 

[Killa_dsm]

Yeah you wont be able to tune with the S-AFC. As stated above I would reinstall the stock 450's and save for dsmlink or EMS to tune.

 

[BklynsDsmer]

ok i just put back the stock ones in, and still the same feels like it wants to turn off , dosent wana idle right . have the safc all at zero low and hi. tr

lets see , on the a/f gauge stay at lean and when i rev a lil i goes to optical but wont pass 3.5 k with out sounding like it had fuel cut off . boost gauge dosent look like it ever moves wether i rev or not.

so let me know if you think i should do something differnt

ty for the replys

Boost Leak?

 

[bento]

1050cc injectors are over kill for a 50 trim set up. You should go with 750-850ccs and get dsm link and a fuel pressure regulator as you are over running the stock regulator with the 255 fuel pump and those big injectors.

Your best investment with an SAFC is going to be a logger. Start off by pulling a plug and checking to see if they all could have fouled using those injectors. You were probably spraying a massive amount of unneeded fuel into the combustion chamber. Then I would do a boost leak test to see if you have any leaks that would cause the car to run even richer. This can be easily done here. IC Pipe Tester Then come back with results from that. If you have time I would check the wiring of the SAFC and make sure it is right as well and make sure you have the MAF signal correct. Your stock boost gauge is going to do nothing for you. It's just there for entertainment. You need to get an aftermarket one to accurately measure boost and vacuum. Also you need to work on your spelling, grammar and choice of words. Also the signature does not follow the rules so you will want to change that before you get any problems from a moderator.

Already has one. And those injectors aren't necessarily overkill. There are more then he will need but better safe than sorry. Just depends on his power goals or future goals. He will need DSMLink to run even 750's so why not get a little more just to be safe.

 

[BklynsDsmer]

i have a upgraded aem fuel rail, afpr, i have the whole upgrade for the fuel sustem just no dsm (ecm) to control those things .

 

[BklynsDsmer]

ok just did the boost leak with the ic pipe tester idea and no leaks holds up pretty well.

so far its still acting up. gona see if ill just take it some were and mayube they can get it to act right.

Will keep posted with more info.

ooh and stroked98tsi checked the safc wiring i did change one thing i changed it to karman cause of the wiring .and still same

 

[PIMking]

Whats your fuel pressure set at? did you set it with the vacume line off?

 

[BklynsDsmer]

its set at 35 with vacume line on.

Update ( Turbo Blew ) Started blowing white blue smoke everywere..

 

[BrooklynBomber]

i know it sounds really bad but check and make sure you didn't put the fuel lines on backwards. from what you said it sounds like it might be routed backwards... it happens

 

[PIMking]

Well you are suppose to set the fuel pressure with out the vacume line off ans 2gs are 43 psi I belive.

 

[All_Boost16G]

Why don't you get a chip from Dsmchips.com. cheaper than ECMlink.

 

[JEFFREYCASTGSX]

Is the AFC set to karman, and set to run on 4cylinders?

 

[95GSXCO]

its set at 35 with vacume line on.

Update ( Turbo Blew ) Started blowing white blue smoke everywere..

Got to love them ebay turbos.

 

[BklynsDsmer]

yea its set n 4 cylinder and on karman.

yea i can just get a chip but no real tunning after you know, better to take the bullet on time well not with a dsm. .. better to go ecmlink atleast thats what i read and heard..



hmmm fuel lines backwards???? ima chek it out..

ok just orderd a new turbo lets see what happens.

 

[BklynsDsmer]

hmm though it should of been 35 ok ima re-set it

 

[BklynsDsmer]

was my mechanics fault wrong inlets on the lines not enough oil, dum phu*er

 

[BklynsDsmer]

ok finally just got my turbo . just sent the ecu to get an ecmlink put in, lets see what happens.

You will love Link!!! I promise.

I just got my car over to the heated garage and will be working on it all day tomorrow.

My hands hurt because I was trying to get the an fittings on the ss fuel line but come to find out the SS fuel line that extremepsi provides was too big by a little bit and had to go to danger zone to get some more fuel line.

 

[BklynsDsmer]

Ok for now i put in a dsmchip stage 3. everything actually running good!!1.
Gona get a ob2 line so i can run log before running it. should i leave the safc on or off?

 

[Gregory]

Glad to hear you got it running ok. I think your problem originally was that you messed up your fuel trims when you had in the 1050 injectors, and they need time to reset themselves. The cars generally do run like crap when the trims are way off. If you didn't all ready, I would have tried resetting the ECU by unplugging your battery for about 20 minutes. That should ave brought your fuel trim back to zero and you should be good to go with the stock injectors.

 

[BklynsDsmer]

yea its running good at idle no more krazy up and down on the rpm and i actually got to pass 3k..

chip is great aint gonna lie. yea i tried doing the reset with the battery but it dint work.
Only think im still looking for a good logger any suggestions? ive looked into the palm m130c but dono if it would be compatible. I was really trying to log from my labtop but couldnt find any forums about it. only seen from palm to labtop or pc. I know theres a cable i gota get .

also looking for info about knock..

I read forums about it and so far i understand that the 2gs cant accurately read knock??

So if any one could give info lets me know.
