Almost all the CPR problems have come down to one of three things: the distributor, the wiring or (rarely) the ECU itself. When people have problems we find that all of them so far have got the CRP to work, but it takes some substitution to find out where the problem lies. If you have altered the original CPR wiring then it may be more difficult - for some reason people try to eliminate or merge the CPR ground (wiring tucks FTL), and then it will never work.

Wow tech support on a Sunday.

You guys are great (well let's hold the applause untill I figure out my problem.

I switch dizzy and nothing same problem.

I have will post detailed pics of everything.

I have another s300 and jumper harness on the way.


Coils are brand new could they be the culprit?

Did you view the catalogs and calibration file?

If you see on my wiring the icm yellow and red wire is linked back into the harness And not straight into the ecu plug. It go back to 2 different pins on my obd2b harness.

If I put it straight I to the ecu my tach doesn't work .

Car is a 2001 obd2b integra Gsr

Yes, all are solder in, as for the yellow icm wire I have since rewired to stright in the ecu and have ran a wire from my tac to the green tac wire on cpr harness so that my tach works and icm wire is not going back to the harness.

Or does that not even matter?

Try putting the grounds on the correct location which is the threaded hole on the thermostat housing that also has the fan thermo switch in it.

Ok yes I will try that. Would it help if I also ran a ground from that to my battery neg terminal, to beef it up a little bit. Any thing else you suggest before I hit another event. Ifo is comming up and it need it no fail or I have to switch back to dizzy!


What about the icm wire the way I had it? Would that affect the function?

Only reason I ask is because I ran my tach off of it now I have to run an extra wire to the engine bay.

The calibration shows the CPR output is switched and the datalog shows the ALTC cycling. That's about all we can tell from the calibration/datalog.
