2 things bugging the crap out of me right now. 1 when I start the car and it's cold it will not rev out and 2 when I blip the throttle I get a tip in lean reading from the wideband? I thought the cold running problem might have been the warm up enrichment settings but that's not it. I think it has something to do with the lean tip in. When it warms up it will rev out but still have the lean tip in.

have you checked your throttle enrichments? iirc there is a tps vs ect vs load table that may need to be set...

tried mucking around with it again yesterday and didn't work. Going to try and double check the wiring to the map sensor and start a new map from scratch. This time I'll use the RB26 calibration file since it's the most complete vs the Rb25.

Got it not not lean out. Throttle fuel enrichment seems to be the key it was at zero on the map. The AEM maps for the RB's seem to be set up for TPS fuel and not map based. Duno if I'm going to keep messing with it lol. I like to hang out with people on my days off. I'm going to prob find a shop that can tune the AEM.
