ok right now, i have stock 19lbs injectors on my car (2.0L for those who dont know) but i have some srt stage 1 injectors that i need to put in because i am finally going to turbo the car. what are the things i need to change? i think i need to change the acceleration enrichments, cranking table, and my req fuel. do i need to change the ve table at all? or is there anything else i need to change, or something i mentioned that i dont need to change?
You'll probably have to do a lot of tuning. VE table will most like change some (although changing the REQ_FUEL will get you real close). All of the enrichments will probably need to change. This is the reason why you only one to buy injectors once. Re-tunning is a bitch!
Its not that bad if you have the parameters set right in auto tune. A 15 minute drive with auto tune, smooth out the VE table, then a 15 minute drive with auto tune will have you back in the game. I was going to upgrade to stage 1's but now I am just going to buy some 750's and be done with it.
yea I heard autotune is a great tool too use. I need to break out the manual and figure out how to set it up. I agree though changing the injectors will screw everything up. I upgraded to returnline and a bigger feed line to the fpr. Much more fuel....although starts and idles fine...well you see my issues in my other post in here. I just need to add timing and start adjusting the fuel map all over again.
I have always used MegaLogViewer (MLV) to tune the car, it works great. I drive for 10-15 mins, datalog the car, pull over, run MLV and tune the map then load it once its done, they drive somemore. its real easy.
I havent used autotune yet so I can say anything about it
