Dear members,
I currently owe an ecu that I bought froma a modified sunny GTiR and the seller, told me that it runs up to 1.2bar and Z32 maf. It also mentioned that at 1.2 bar it produced 340bhp (338.7bhp). He did not mentioned anything about the injectors though. What is your opinion concerning the injectors. Should I go for 550cc or stick to the 444cc that the GTiR uses ?.

Great thanks for your assistance

You should find a tuner guy or somebody that he can read the program in your ecu for the right setup of injectors, maf, ect....

Don't guessing or a big risk of loosing your motor !

444's should hit 340 but that is maxing them out

I would go to the 550cc or run your stock injectors at a higher fuel pressure of 4bar. I think if you run 4 bar it brings you close to 520cc ish

Damn right !

- the map on your tuned ECU is for a specific injector size...

To run 235whp / 300bhp, check out the other thread:
