Shift light logic to control solenoid and TCC logic

Hello I need help with an 1227165 MAF tpi ECU. I would like to retain TCC logic as it is now but also use an up shift light output at set it to 4000 RPM. I would need to have the shift lamp logic output to a different output somehow. What I'm trying to do is have the ECU output a signal to operate a solenoid after 4000 RPM. I have a vacuum controlled exhaust dump valve that I only want open after 4000. Now I have it on a WOT switch at the throttle body but I prefer RPM logic to WOT logic. Any Ideas?

Need to get the hac of the mask you are using ($32 or $6e) and modify the code.

Re: Shift light logic to control solenoid and TCC logic

rather than modify the ECU code why not install an RPM switch like the one used for nitrous.
