Re: Tune after Upgrading afm and injectors

Sounds like base fueling wasn't setup properly after adjusting K for load If you lifted the whole map up +13 to get rid of the negative values, and then readjusted TIM (removing fuel) your top end would then be 23 values Yes 1000CC result in quite a flat fuel map, since there is less trimming of bas...

Re: Changed injectors, MAF Translation?

I'm not sure last question. Yes if you ran races and compared old/new MAF with adjustments until resulting AFRs were the same in the trace then you should be fine (injection time should also probably trace the same between old/new)

Re: Nistune hang up when trying to use Active Tests

More information, like which ECU were you using? Can you supply a debug log?

Re: EDM S14a SR20DET>SR20DE conversion

I haven't made a youtube video, someone else's. But normally I would leave as Z32 load and then adjust K constant until the cursor reaches the end of the load map

Re: Changed injectors, MAF Translation?

Looking at changing the MAF tube size with the HPX, the whole curve gets shorter/longer

Re: Z31 non turbo ecu with turbo idle controls

There should be no difference between NA and turbo hardware, apart from the knock sensor board

Re: Flex Fuel Gauges

Expert mode:

Display > Consult RAM tracer

Trace address 1401 (diag input) length 01

Let me know if this is 00 or something else when there is the voltage input on the diagnostic line

Re: Flex Fuel Gauges

Check installation of the flex board, and that there is about 5V between black wire and green wire using a multimeter in the ECU

Re: Changed injectors, MAF Translation?

Thanks. Going to be a long one... foot got pretty messed up and needs multiple ops With the MAFs, once you change the tube size, it will need recalibration. To get an idea of what it looks like, play with the MAF scaler tool using the HPX/R35 sensors. With the HPX I have the polynomials to generate ...

Re: Z31 non turbo ecu with turbo idle controls

Auto trans ECUs adjust idle differently for the torque converter. If you changed to manual, it may operate differently. Depends when the problem started (after the trans swap) or otherwise Speed signal comes from the dash cluster as a PWM input, and gets its signal via hall effect sensor in the tran...

Is flex fuel enabled, is there ethanol in the system? They wont display a reading unless above 0% ethanol

Re: No start after maf calibration

Okay copy in K and crank enrich maps from the factory tune (File > Import selected maps from file) and then select those two. See if it starts with that to get you going

Re: Lambda ecu on non lambda car

There are some differences between the lambda (39Fxx) and non lambda (44Fxx) ECUs. Including the O2 sensor, cat converter and the MAF wiring at a minimum. I'm not sure on the other differences between the two models as to why it is cutting out. It would be a good idea to take a log, including the AF...

Re: EDM S14a SR20DET>SR20DE conversion

What size pipe is the HPX N1 installed in? What curve did you select? It shows as 'unknown' in the tune file you posted

If it goes rich then the curve may be too 'steep' perhaps and the sizing does not match the pipe/bung size. At a guess
