Re: strategy swapping

Does it have to be a f3 or could it be a ti chip?

strategy swapping

So from my understanding it is possible to tune something like the 8ld with a a9l strategy when using a quarterhorse. Would that still apply if I burned a chip when done or would I still have to have the quarterhorse connected to work right?

Re: at a loss

at a loss

So about 5 years ago I built my current fox running 06 take off 24lb injectors using a c&l 76mm mass air and it ran pretty good. Decided to swap to microsquirt and ran it for around 4 years, which brings us back to current. I decided to swap back to my a9l and use my quarterhorse I picked up a couple years ago and I can not get the car to run normal anymore. ive gone simple to start and used the c&l transfer numbers, 24lb numbers from efidynotuning and turned off the three smogs. and it just goes lean. Ive gone as far as turning only smog stuff off and just using the MAF as is with being calibrated for 24lb, used stock maf and adjusted injector settings and still the same. Currently with stock meter and 24lb injector settings I have to add around 50% to the maf curve to get afr around 15 (running a wideband as well as the narrowbands). What or where can I look? Car has trickflow upper and lower, lunati cam (clone of tf1) brodix st 5.0 heads. Thanks

Cold Start swings lean after 30 secs

A9L2 so, I dont have my wideband connected to the ecu yet (spartan WB) need to take a min and do the voltages. Anyways from a cold start car runs fine, after about 20 to 30 secs my wideband shows it start swinging lean all the way to around 19.5. it hangs out there for about 30s and then slowly swings back to 14.8-15.2 as it warms up. Would that be startup enrichment? or cold idle enrichment? from a warm 180 degree restart there is no swinging AFR's
