Having problems tunning with new 650cc injectors with the APS TT kit with the unichp. Has anyone done this yet?

 

I have....it ran fine, but didn't idle so great. I'm having my ECU reflashed as we speak; I'll let you know how it goes asap. Maybe Tuan at GRD could chime in....

 

unichip doesn't have scaling capabilities so you won't be able to get them dialed in. Unichip works by % up or down and the 650 cc injectors will require adjustment out of the range when the ECU is scaled to the stock injectors. I would recommend a EMS that has scaling capabilities like Utec, or you can do what FailSafe did and flash your ecu for your injector size

 

thanks for the info.
