I just installed 60# injectors, 255lph fuel pump, 3-bar MAP, adjustable fuel pressure regulator, and 91 octane TT chip set up for the mods on my ‘93 Ty. I also have an AEM wideband that I installed prior to these modifications which would read fairly normal numbers.
After the modifications, the truck is starting at about 14.7 and then immediately shoots up off the charts lean. I know that it needs to learn the chip, so I stayed out of boost and drove slowly around town for about 15-20 minutes and then let it idle another 20. At no point did I get an AFR reading- it stayed completely leaned out.
I don’t have my wideband connected to F14 yet but plan on doing so. I turned up my idle fuel to max on the chip and still did not get a reading.
Any ideas as to what is going on?
