sh4d0w Posted December 2, 2019 Report Posted December 2, 2019 Hi I just installed 1200cc injectors I had 850cc injectors before. I changed my master fuel to 8ms it was 9ms before. The minimum pulse width for the new injectors is 1.8ms and I think this is causing a lean condition when at cruise because the actual pulse width is falling below the 1.8ms. My questions is how do I set a minimum pulse width in link g4? I see forum posts about how to set it with a g4+ but i can't find anything about the g4. Can anyone help me out please? Not sure how to get the injector pulse width to never fall below 1.8ms Thanks in advance for any help! Quote
Adamw Posted December 2, 2019 Report Posted December 2, 2019 There is no such feature in the G4. Assuming the AFR is running close to target under most other conditions then you will just have to adjust the cells in the main fuel table in the high vacuum/cruise areas. Quote
sh4d0w Posted December 3, 2019 Author Report Posted December 3, 2019 Thanks adam, O.k so what if it's not? At idle i need to have the car running at like 12 afr for it to run properly. What is the best solution for this? I was thinking of lowering my fuel pressure to 30 psi instead of the current ~40psi. This would bring the injectors down to like 1000cc instead of 1200cc would this help? Regards, Quote
Adamw Posted December 3, 2019 Report Posted December 3, 2019 If thats what AFR your engine needs to idle happy then so be it, run it at that. It is more likely a poor spray pattern problem than anything PW related since they will be a decapped injector. Quote
