Had this RX7 for a lil over a month, and she always been running rich. But I feel its a lil too much. Damn near gave the people behind me carbon monoxide poisoning being in mcdonalds drive thru for over 15 minutes. They actually got out the car and asked me to turn mine off! haha Anyways, for the specs.. At initial start up, AEM reads 12.9. After warm up, it drops to 12.2 - 12.4. Normal cruise, im right at high 14's to mid 15's. The vehicle mods are the Rtek 1.7 chip with the recommended fuel injectors, HKS intake, and performance exhaust. The turbo is ported out a lil to. Vacuum is at 18 INHG. A/F range holds around 10.2 under boost. Car runs awesome, just smells like a *****. Any tips for regualting this would be awesome. Thanks! Brian

 

Rotaries Idle rich, you may be able to clean it up to 13 AFR at idle but that is about it. Cruising at 14-15 is great, As far as 10.2 in boost that would often create rich misfires.
