s300 incorrect rpm reading

Post by kablammyman »

After using turboEdit for years with my turbo 89 integra, I made the jump to obd1...well, I tried to anyway.

My car has
255lph walbro fuel pump
DSM 450cc injectors
t3 turbo etc
plx m250 wideband

With turboedit, the car ran fine (well, there was no issues besides turboedit itself, lol) so I decided to get some trouble free engine management by upgrading to obd1 using this guide:
http://www.g1teg.org/forum/viewtopic.php?f=14&t=35678

After not being able to make my own ecu harness, I bought the g1 integra specific conversion harness from rywire.

So, the car runs, but poorly. When datalogging, most of the gauges seem to read correctly except for the rpm. It reads from about 100->200rpm, while the car is running at idle (around 850 rpm)

Also, when trying to rev the engine in neutral, it will sputter and backfire. After that it will soon die.

I'm not sure what else to do now, so I'm looking to get any help I can get.

Thanx

Have you tried the ECU in a known working car yet?
