I've got a new camaro with a TVS1900 that I'm having trouble with getting it to kick out of closed loop. The PE enable TPS table is labled as "HOT" and is apparently just that since reguardless of what I put in the table it doesn't leave closed loop until 55%. The problem with this vehicle is that at low rpm it will make 3-4 psi of boost on as little as 30% tps. And under that much load its to lean for it to run right and bucks and hunches until you either get out of it or get on it enough to hit pe.
This is a problem I've never had before because any blower car I've ever tuned that was this new has always had a centrifical style blower or a turbo, and low rpm - low tps boost is not a problem. And obviously most older style ecm's have both a "standard" and a "hot" PE enable TPS table so get it to do what I want isn't a problem.
Also I noticed the OL lookup works a little different than in the past vs the newer computers. If I disable CL via the temp thresholds is works just like the older pcms. If the PE EQ is less than the end result of the OL EQ, it goes with the OL EQ value. This lets me use the IVT Gain table for boost enrichment. Set the pe table to 1.13 across the board and let the IVT Gain table pull it down to 1.22 or so once you get into boost. But after you enable CL, when it does finally see enough tps to kick into PE is just goes with the PE value reguarless of if the values of the OL tables is richer or not. That stinks...
So what I'm asking is what are the rest of you guys doing on newers cars with positive displacment blowers that only have a "hot" tps PE enable table?
...and to the HPT people - Is thier any plan to add the normal operation tps PE enable table to the newer calibrations?
