Figure out which code it is throwing and fix it.

actually it was me that started this thread, and I check the code and it throws no code, it just stays solid and doesn't blink. so if you could enloghten me oh smartest of the smart, I would appreciate it.

i tried calling but couldn't get a hold of you. I have been doing some reading and it looks like the causes of a solid check engine light with no code could be one of the following. Shift light setting low (making the light stay on all the time with no code). it was also said that it could be caused by a bad chip, or a chip (rom) that was ordered for a different ecu. It could also be the injector settings but that usually results in a readable code.

When you get a solid CEL like that, generally it means the ROM (Chip) is bad. Are you using the romulator or the chip? It is telling you it can't read the bin file to start the car. Try reburning it. HTH

yeah I think I am going to try and throw in that other base map with the three bar map and see if it goes away...

If the ECU is hondata prepped and they cut jumper J12 as hondata reccomends, you will NOT be able to pull CELs via the service connector.

Cool. Didn't know that.

nigel

wow really?

PHiZ

The way that I understand it, J12 is responsible for full/half duplex operation on the CN2 port.

When you cut it to enable full-duplex (and greater hondata interface reliability), you are "hijacking" what would usually be used to drive the CEL.

If I'm incorrect, I welcome a correction. Or if someone can test it out real quick...

I need a new base map. does anyone know where I can get one?

rcfast

so the 3bar worked without a light?

thad

this is nigel...

I got the basemap to work, and the cel went off and it idled perfect and warmmed up smoothe, and then I started playing with the gas and revving it up and down, and then the rpm's got stuck at 5000 and every time I start it it goes straight to 5000.

what the hell do I do. I am confuesed does it have anything to do with wide open throttle shifts?

any help will kick ***!

My P28 doesn't have J12(we took it out) and I can still pull codes via the service connector..

Huh?
The only way this could happen is if ther was enough air going into the engine to keep it at 5000 RPM... sounds like the TB is stuck open, or you have a real bad leak (like PVC valve off), or you plugged somthin in wrong (like swapping the MAP/TPS plugs).

The 2-stage shift limiter has nothing to do with this- it looks for the clutch signal and re-sets the rev limiter to a lower level when the car is moving (VSS sensor &gt;0 mph).

If you don't get a CEL then stat by checking the TPS voltage when the TB is closed (should be 0.45-0.47 VDC)... if that's ok, start looking for leaks!
