I was going to install all my gauges before installing my turbo just to decrease the install time of the turbo kit. Would i be able to use the FI/C when the car is just stock?

 

You COULD use it - If you know how to tune and dont have to pay a tuner then I guess it would be possible....But if you are paying someone to tune it, it would be pointless to get it tuned for your N/A setup and then get it re-tuned when the turbo was installed - Hope this helps

 

Why plug In the fic if your not turbo yet. Unless your Going to either tune before and after the turbo? Lol

 

IMHO it is an excellent idea to install the FIC before the turbo. Doing so will allow you to log your MAF so you'll know where to clamp the MAF post-turbo and test the FIC/wiring/harness for any problems. You could also create a O2-AFR table for tuning the O2 map later. You may even discover that you need resistors on the crk/cam inputs or that you need to remove them (as I did). In short, it could save you a lot of trouble shooting and guesswork later on.

All you have to do is set the MAF map to percent mode and leave it filled with zeros. The O2 map can be in voltage or percent mode. Zero = no change. I wouldn't change anything on the fuel and timing maps. If you encounter any issues running the FIC stock, you'll know that the problem isn't your turbo installation. You can always install the bypass harness if you need to remove the FIC. The car should run exactly like oem with the FIC installed and properly zeroed out.

 

Elevation posted an aem stock tune a couple of weeks ago...shouldn't that map work as well? I was thinking of doing this as well

 

Ok that's what I was going for. I didnt want it to be tuned or anything. Just mainly log wyhat I have going on in my car. I'm just trying to make my turbo install as easy and problem free as possible.

 

^^This

 

however idk why but the bypass harness didnt work for me

 

definently a good idea to go ahead and hook it up. I did what was posted above and never encountered any problems. I was turboed but i pulled it off to get my turbo seals replaced so now im stock and still running the FIC with no problems. It will give you a good chance to do a couple of data logs of your stock car for future reference.

 

I installed mine but put a base map on it and did the injector size change...it worked out pretty good but i dont expect that to work all the time.

 

so loading the FIC with the Base Cal.fic6 is basically all i need then? because everything on it is all 0's. with that nothing would change and run like stock?

 

not exactly...i found atleast on the tc that setting the 02 map to percent and map left zero'd will run for a few miles then throw a code and make the car run like crap...i suggest instead is to set the o2 map to voltage and fill in the map with 3.2 or 2.8, that should get ya running.

the base cal you will still need to go to the setup window and change maf to percentage

 

alright so leave the maf map zeroed then put the 02 map to 3.2? would there be any difference on leaving it at 3.2 vs 2.8?

 

yes...there is a difference. 3.2v in the perfect situation should produce an afr of 14.7 and did the first time i boosted but now 3.2v is 15.5-15.8 afr now so i needed to lower the voltage

 

alright. i'll try it out at 3.2. and can you email me a base map? after reading a ton of threads about basemaps... you seem to be the go to guy!

if you can my email is ejmartin@mtu.edu

if anyone else can... an email would be appreciated!

 

i just installed it today with the MAF map being all 0'd out and then the O2 map being set at voltage at 3.2. everything ran fine except my idle was about 150-200 RPM lower than normal. what would get this back to normal? injector response time? it's at 486 us right now. i don't know if that really matters too much since it's stock and i've been trying to find the stock response time too.

any help would be appreciated

 

you could play with it a little and see. perhaps try 1000us and see what that does for ya.

 

3.13 = 14.7

 

not on all...thats why i said between 3.2-2.8

 

btw do you have a scangauge? to find the best value for you since your running stock right now is to look at your fuel trims, if they are over +-2 at idle you may want to add or subtract voltage on the o2 map. get it as close as you can to 0, once youve found the butter zone you will now know the exact voltage to use for other areas (closed loop).
