Link doesn't work for me. You can email me the log, eric@turbotweak.com The closed loop/open loop operation is normal for the TT chip.

The 3 bar map has a completely different calibration than a 2 bar, and the map has to be matched to the chip. The EGR is not used in that chip, so that byte of memory is used for something else, so just ignore what you see on DM. If you can email me a datalog from DM showing the problem, I'll be...

Re: Low Fuel Pressure Fuel pressure gauge working correctly?

Re: Running Way too Rich AFR Help! Please If you leaned it out until it died, then can we assume the wideband is wrong? What kind of wideband? Do you have a gauge for it, or just through the ECM? Are the injectors actual Siemens 60's or replica's?

Re: Wicked Rich Idle Yes, pin B9 is the recommended place to ground the wideband (or the case).

Re: Wicked Rich Idle Fuel pressure jumping is not uncommon with big injectors and batch fire injection. Also depends on the gauge, as some gauges will dampen the pulses. The fluid in the gauge can sometimes "thin out" when hot. If the wideband and scanmaster match at first, then don't match...

Re: Data log file help( aldldroid) I would use the dial first, since it's permanent and can't be lost if the ECM loses power. But, to be clear, you are adjusting it because the correction is bottomed out, not because the AFR is 10.8. You need to define a target AFR, then adjust the fuel until...

Re: Data log file help( aldldroid) No, you don't need to change the dip switch settings. You can change fuel and timing with the chip parameters. Base WOT fuel you can reduce by turning down the WOT fuel dial on the chip.

Re: Data log file help( aldldroid) I got it. I see a little bit of knock retard at WOT, 2-3*. I would reduce timing a degree or two to see if that helps. It's also a bit rich for your boost level, 10.8 AFR at 13psi. I see you are running it in closed loop WOT. What AFR are you commanding? The...

Re: Data log file help( aldldroid) Yes, but could you send the tunerpro format, not csv.

Re: Data log file help( aldldroid) You can email me the file, eric@turbotweak.com What are you seeing?

Re: Aldldroid help!!!! You'll need a file management app to put the adx where it needs to be, or connect your phone to a PC and manipulate it that way.

Re: 2 Issues Fuel pressure question/stalling How far away is the end of the fender dump from the O2 sensor?

Re: 2 Issues Fuel pressure question/stalling Fuel pressure should start at 43psi line off. It will drop 5psi or more when you put the line back on. What is your air/fuel ratio at idle? What is the IAC reading at idle, warmed up, in park? What is the BLM reading at idle?
