bigger injectors-what needs to be changed - SRT Forums

CASPERAMC · 09-11-2007, 12:24 PM

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?

thanks

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!

Thats why im going to take out my 19lb'ers first and swap in S1's first then tune those injectors!

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.

autotune is ok, i prefer to use the ve analizer in the logviewer

That worked pretty well for me.

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
