The AFRs were going way too lean when attempting to tune on the chassis dyno with the Rtek-chipped ECU. Not sure if the ECU I had the chip installed in was defective. Sent the unit back to Digital Tuning to verify that their chip was good and they indicated it was good. Sent the RC injectors back to RC Eng. to verify they were good and they were good. I reinstalled the original ECU and had the car tuned with the S-AFCII. Car tuned with a safe AFR and it runs great on the track. Needs a bit of tuning at low/zero throttle settings I think 'cause it is a bit hard starting and needs to be helped with the throttle once it starts until it runs for a minute or so.
Definitely put the car on the dyno before you run it too hard with the mods. Rtek 1.7 purports to be mapped to 720cc or so secondaries, but like Reagan used to say, trust but verify.
