Default Any maps for a 91 with variable tps and Boost control?

Does anyone here have a config file for 90-93 /Variable TPS/ boost control, so I can look at and compare the Accel/Deccel information and Boost Control setup?

Boost is great but still bucking, fowls out plugs, and start up sucks. Driving downstate to the track in the morning and I guess I will just deal with it. Ugh. Why did I have to go standalone again?.

Well I have a 1990, but with a 97 1.8 in it. I'm running 460cc rx-7 injectors, Nissan 240sx variable TPS, but I haven't configured the boost control yet. I'm using an external boost controller, but will be testing a GM solenoid hooked up to the EMS tonight. Is your variable TPS working properly in the EMS? Does it ever read 0% or 100%? Start up takes a few crank cycles, but that's normal for the AEM EMS on our car. Once it's started, runs perfectly. Very smooth transition in throttle, etc. Tell me if you want my map.

I haven't tried the 2% to 98% change, is that really it?

Yes, I want to compare maps no matter what but I would prefer after your boost control is working. Mine clicks like it should but never closes the controller.

Well here's my most current map:

I'm using the GM boost solenoid for boost control, and I'm presently using the VSS advanced boost option. I understand our cars don't have a VSS, but I was just trying to get one boost level, since I was spiking quite bad with my other setup. It spikes a bit now, but otherwise is stable. I'll be switching over to a RPM based boost control in the next couple of days.

Also, I'm using the AEM 2 bar map sensor.
