Your settings look alright, I would increase the DC% to 50 or so, and set your Gain to 6 (if you have boost oscillation issues, then you can lower the number).

Thanks, this was helpful. I ended up increasing my DC% to 50% and then 75%, now I'm seeing a relatively steady 15 PSI at WOT.

Do you know if there is an easy way to monitor/log timing (always reads 0) or knock on the maftpro/tunerproRT?

The T-Pro can monitor timing:

Translator-Pro Timing Monitor

*Note: wire the T-Pro to the ECU Tach Output wire instead of the Power Transistor wire*

Interesting, I thought about it and decided that monitoring timing is not important enough for me to physically clip that resistor inside the unit.

I noticed your sig. talks about monitoring knock with the MAFT Pro, how is that done for a vr4? The guide (v1.5) states "Cnt" is only for Porsche 944 Turbo.

Currently knock monitoring is only works for vehicles with an external knock module (like my 944Turbo).

Clipping the resistor isn't hard and repairable if need so.

What is your AfterStart set to? And is this a cold-start or warm start issue (or both)?

Try increasing your afterstart to ~10.0 or so.

so here I am again with the same problem that seems to come and go with my 92 VR4 running in SD mode, I have no complaints other than my LC-1 wideband will shut off, in a sense.. go into calibration mode at random times.. especially when the AC is on, if I use my ac any more than 10 secs the LC-1 led flashes, and begins recalibrating. I switched 12V sources, grounds, etc, maybe a little change but nothing.. turn the ac on, LC-1 shuts down, thus screwing with the maft-pro, and causing a sputtering POS as far as driveability goes..Everything is new,, new wideband, with heat sink bung, recalibrated numerous times.. no luck, one week the car runs fine(Minus the AC in the heat which sucks) run the ac and you have to wait about 2 days to drive it.

Any suggestions, hints, etc,???

any and all info is greatly appreciated

James G

Have you tried contacting Innovative? Perhaps your WBO2 is faulty and needs looked at/repaired.
