I got my tt 225 injectors installed today and the 1+ flash from apr. It was driving really until the boost became limited to under 7psi. I turned the car off and put it in stock mode, which was not going above 4-5 psi. After changing into stock mode and driving on the highway for a few minutes I through a CEL (0171 code (lean)). I stopped for a minute and cleared the codes and the CEL went away. I then drove an hour home and an hour back to school and it drove perfectly without any boost issues or fault codes. Is it normal to have a fault right after getting injectors and stage 1+ flashed? My car is driving great right now and has been for the past few hours so I am not too worried anymore. anyone else have an experience like that?

 

i bet its just the ecu getting used to the new hard ware and ur car went in to limp mode
i hope nuthin else goes wrong
with larger injectors i thought u would go rich instead of lean

 

I would have thought the same thing, which I saw lean I was really confused. The CEL came on when I was in stock mode too. I cant think of anything that it could be because it is running perfectly now.

 

maf........ maybe a thrust sensor........ both problems i had with that code, and i went into limp mode.... so did my car


lol

 

I hope its neither of those things... i just drove around tonight(now that the temperature dropped a lot) and I definitely felt a huge difference with the injectors... apr stage 1+ is a big jump from stage 1

 

congrats.. keep in mind not only do you have new injectors, but you have different software tuning now too. So Boost and fuel are beef'd up. Hopefuly its just adapting and you wont have any more issues. It happens.

 

Sounds like your ECU is dealing with the change, go easy on the throttle and let it realize whats taking place.

Sounds like your car entered limp mode which isn't nessecarily uncommon when making such changes, just let us know if it occurs again in the next few days.... Even if it occurs tommarrow it still might be alright, but if it keeps on doing it there could be an issue, but it sounds like your alright to me.

Enjoy the chip man, I'm sure its awesome!

 

yea I am definitely enjoying it.. the stage 1+ is amazing... it is a completely different car. thanks for all the help guys. and amze.. you need to get a chip already man haha

 

Yeah I know, =( I'm trying to save man but insurance is raping me... plus I just quit my job... sigh sigh.

 

If i have APR 91, can i jsut throw in some injectors and the car will be fine or do i have to get new software for the injectors???

like 310 injectors
