offro Posted January 14 Report Share Posted January 14 Thank you all for everything you have done. Sorry for all the questions, as this is private. I was able to bring it from engine start to idling. However, I have two problems. 1. it is hard to start unless the accelerator is fully opened when starting. 2. after reaching the target idling value, the rpm keeps dropping and the car stalls. Specifications Model: HONDA CR-X Engine: B18C Engine specification: ITB 4 throttle DBW ITB vacuum surge tank used I am thinking that changing the idle Posn setting will stabilize the idle RPM, is that correct?

Adamw Posted January 14 Report Share Posted January 14 I would say the main issue is you dont have enough fuel. You can see the lambda is already very lean at 1.4 when the sensor starts working and it continues to get leaner as the post start enrichment is removed. Try adding about 50% to your master fuel number and adjust from there. Also your MAP sensor is reading wrong, this wont affect fuel, since it is not being used but will affect functions which use MAP or MAP delta for lockouts etc. With the engine off the MAP should read about the same as BAP (~101kpa) Quote Link to comment Share on other sites More sharing options...
offro Posted January 14 Author Report Share Posted January 14 Adamw Thank you very much. I had overlooked the lambda numbers. I will adjust the fuel. I will try the MAP calibration again. I will set it up and check it out in the next week or so. Quote Link to comment Share on other sites More sharing options...
