For fuel I have the walboro 255 hp, the supra 440cc injectors and I'm tunning with the SAFCII. What size were the stock injectors? Why when I'm in low throttle loop (actually idling) and set the SAFC II to -50% am I still at 10.3 to 1 A/F ratio?
I brought it to get it tunned today and the guy wouldn't touch it because it will not even idle at above even an 11? Please help me out; I need my car for daily driving in the summer and I will only have a week to work on it before I start my summer internship. Thanks for the help, Derek |

d0w0rks0n, your problem is because 460cc injectors are WAYY too big for the 7A. The stock injector size IIRC is about 172cc or 192cc. Somewhere in the 300-400cc range is appropriate for the turbo 7A, anything more than 400cc is going to be very hard to tune properly. My 315s were ok with the SAFC, once I moved to the 370cc injectors I couldn't tune it right with the SAFC and had to upgrade that as well.
As for the original poster, I have no idea what engine you're talking about but if its also a 7AFTE then your injectors are too big also, if its a 5SFTE the size is ok and its probably an issue with your method of fuel management and/or something not hooked up right or something, any other engine, I have no idea. -------------------- |
