ok, I am new to the FI. I am slowly getting every all the parts together for my turbo for my h22. Currently i have a chipped P13 and vafc. I am planning on using the vafc hack + dsm 450's. My question is will i have lean issues with the chipped ecu? do i need to get a different chip? Any suggestions?

 

Depends on what your ecu was chipped for. Most likely it was chipped for n/a performance so it's going to have a more agressive timing curve then you want. I would say run a stock ecu.

 

if thats the case can anyone on herre make me a better chip that is closer to stock or to better fit my mods?

 

anyone else have an opinion?

 

... the n/a chip is definitely bad news for a turbo application... the timing to prolly advanced too much that you would detonate if you use it with a turbo... if you wanna run stock again, you can just cut the jumper at j1... but if i were you, i would look into this... with it you can retard you ignition per pound of boost...

 

thanks i will look into that
