CPR break up wont rev, no 2 step help
CPR break up wont rev, no 2 step help
i am staring my own thread I have calibration and datalog.
was at the track again and only got one run it at 10.8 but the damn ignition trouble wont let me get another.
changed plugs triple checked wiring and cleaned all grounds.
sometimes it works flawless other is doesn't I am trying another dizzy today then I will try ecu and jumper harness. but I mean this isn't a new problem for cpr users. hondata always has good tech support so any help I appreciate

Re: CPR break up wont rev, no 2 step help
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

Re: CPR break up wont rev, no 2 step help
Did you solder these connections?
Re: CPR break up wont rev, no 2 step help
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?

Here's the serial in the box I have another ecu comming so maybe that one will work.

Re: CPR break up wont rev, no 2 step help
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.

What about my datalogs and calibration files,
Ou alwYs urge people to post them so I assuming mine are ok?

Re: CPR break up wont rev, no 2 step help
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.

Plost a picture of the ground on your valve cover
