wow. So yeah, I just swapped the injectors and after a little of fiddling with the throttle position sensor I got it running on its own! Thanks so much! Any tips on how to properly set the TPS? There seemed to be a really narrow range where it didn't bog down and where it was burning clean(no tail pipe smoke). Seemed to idle ~1750 at that setting.

Yes.... should the bigger green boys not be the ones to use with the roller barrels? Potentially dumb question, what are they for then?

Hi folks, I'm building a 420R kit with roller barrels and can't get the thing to idle right. The car turns over fine, builds oil pressure. After connecting the immobilizer to get fuel is when problems happen. The engine doesn't spark at idle, only with throttle do I get ignition and then the engine spews out unburnt fuel. It runs so rich that I can disconnect the immobilizer after this and the engine runs fine for close to a minute on residual fuel. My dealer took the ECU back thinking it was mis-calibrated or something and after several months(!!) wait I get it back from Caterham direct and the same situation is happening. My only thought is the TPS is wrong making the engine think it's at WOT fueling level, but I've tried adjusting it to no avail. I also haven't been able to get a hold of an MBE985 cable as they were sold out at SBD motorsports last they asked, but I'm trying again. I will try jerry rigging some fly wires into the TPS to see if I can get some readings. I've read some competing information on what voltage or resistances I should be looking for, anyone have the source here? Any other thoughts on what to try next? Thanks in advanced for the help!
