      This is a rebuilt 390 with a very mild hydraulic roller cam. Pertronix distributor with Ignitor II, matching coil. Pertronix second strike bow (second strike set to 0), new MSD Streetfire wires, Autolite plugs. The engine just runs rough, like it's missing on a cylinder, but it's not. I changed the ignition box once, plug wires twice, and spark plugs three times. I've measure valve lift and they are all within spec.

      Hey Denis, go ahead and disregard those 2 data logs I sent you over the weekend. Gonna troubleshoot this 128 error code and I'll get back with ya. Have a good one.

      I have an IAC alarm of 128 when the engine idles but the F9 screen is giving my IAC status a 15 (normal). The engine rpm's are between 750-1000 like the ECM is searching for the correct idle (it's 800). My Start IAC Pos vs Coolant temp graph starts at 179 and drops to 120 as the engine heats up. On the F9 screen the IAC target is 90. Are these numbers too high?

        Hi J-440, Bring up Idle Functions and select Start IAC Pos vs. Coolant temp you can see exactly what the IAC is doing when your engine is running. In neutral the IAC should be 15 to 20 on that table. If you would like me to look at your tune, email your .gct file to me and I will go over it.

      I bought the Olds Cutlass new in 1965, and have been making it go faster ever since. My latest improvement was to match up the target A/F with the torque curve of the engine and our quarter mile time went from 12.4 sec to 11.96. Not bad for a fully restored car in full factory trim. Engine is a 385 cu in Aluminum block SBC. AFR 195 heads, TPIS Mini Ram intake, XFI 2.01, 10.25 cr.

    My son and I race a 1965 Olds Cutlass with a 385 chev alum. block, XFI Fuel injection approximately 500 hp. Just changed the rear end from a 3.73 12 bolt to a 3.42 8.5 inch 10 bolt.

    Also have a 1990 ZR-1, 32 valve 4 cam Corvette with 36000 miles on it that I am currently working on. May race it once I get it running right. Just installed 16 new injectors.
