I have a B18c with a Skunk2 IM, holley 68TB, 750 inj, 9:1 compression pistons, manley rods, MSD distributor. The problem is when I put my S300 in open loop to tune the idle goes up and down, up and down. When I put into closed loop it idles fine. I checked my IACV ohms at 11.2 set my TPS at .45v. Still idles up and down in open loop. I tried a fresh calibration with no help. Is this a ECU problem? Please help! anybody.

I'm running GSR cams, S300j v1.4.8 Idles smooth on closed loop but when I go to open loop about 5 seconds later the idles goes up and down a/f goes rich 12 to lean 17. I checked my Iacv its good, my coolant is bleed, my TPS is set correctly @ .45v. Timing is set to stock settings. I even tried a new stock calibration and adjusted my injectors. I recently downloaded the new v1.4.8 could this be it? Do I need to adjust anything? Spunkster where can I get the old version 1.4.7 to rule out my problem?

This is my open loop and closed loop datalog at idle with a little reving. Please help with suggestions why my B18c idles like this and what can I do to fix problem. Your help is greatly appreciated. Thanks Mahalo

You have posted calibrations, and not datalogs. without the datalogs it is impossible to see what is happening.
