So recently i put my p28 w/ neptune rtp installed in my new car (1991 civic w/jdm b16 converted to obd1 using rywire harness)

the ecu worked fine in my last car, ran perfect.

threw a p30 stock basemap on it and put it in my new car, fuel pump primes, fuel rail gets fuel but injectors wont spray??

thought it was a wiring problem but i ruled that out when i plugged in my obd0 ecu (and took off the obd1 jumper harness) and the Injectors sprayed when turned over!

what could be going wrong here??

rywire wired the harness wrong?

or somthings wrong in my ecu?

or maybe i didnt program it right?

please someone help its my new DD and i cant drive to work anymore

 

If you can datalog (Push TPS to make sure it's following) then it's uploaded correctly. If you aren't seeing RPM during cranking then you may want to check the CYP signal wires etc.

 

going to try that right now.
brb with results

 

hmm this is really wierd.
I went out hooked up my laptop to rtp,
connected it then hit datalog.
i then cranked it over and they sprayed.
idk if theyll continue to do so once i disconnect it?
havent tried yet.

 

Try. That may mean it's not installed correctly. You should see the LEDs light up when you key the car on without the laptop connected. Is it an old RTP or a Demon?

 

okay scratch that, my idiot friend never connected the p28 to the car only laptop lol. so it was running off the 0bd0 ecu while i was watching the injectors spray...
alright well the ecu does connect to datalogging.
but when i crank it over it does not register rpms in gauge window or anything else...

 

Did you test TPS to make sure it's datalogging real values? If it is datalogging real values then it would be your wiring preventing the ECU from seeing RPMs.

 

This may be a stupid question, but how do i go about testing the TPS?

 

While datalogging, push the throttle to see if it changes in datalogging.

 

yeah, i tested it and it works fine.
the tps percentage goes up evenly as i press down on the pedal.

 

Awesome. Then you have your answer (Covered above).

 

Alright, so i checked out all the connections going to the distributer.
found out most had really corroded solders only electrical taped together.
resoldered all of them now the rpms are showing up like they should!
i took a look while my buddy was cranking the car over and fuel is spraying out the injectors, but the only problem its not much fuel just a little spray.
i put them back in and tried firing up the car, and it wouldnt fire up.
Its just not getting enough fuel now.
The only code its throwing up is knock sensor malfunction.
im just going to bypass the knock sensor, but what would be causing the fuel problem?

 

Your settings. It's a tunable system. Make sure it's setup appropriately.

 

please refer to the help videos which can be obtained within the software under the help folder

 

I redid all my wiring and soldered+heatshrinked, and resoldered my main relay just cause i could, along with undoing all the plugs in my harness and re-plugging them back in just to make sure of a secure connection.
The injectors are spraying alot more fuel now.
but the car still isnt starting i'm sure its somthing i can figure out on my own from here.
Thanks for the help guys.

 

Glad it's working now. Tuning is always a process. Enjoy!
