More tunerpro help

[jman093]

First test and tune at the drag strip is this weekend. Going with a buddy running an RX7. Trying to work on the tune at the last minute here after having all winter to do so. Car has some sort of aftermarket turbo on it and was hitting the 8.32 psi overboost fuel cutoff (code 31) on the track when I went last year when we went. Could only go 15.4 with the car cutting off fuel like that throughout the run.

Editing the boost tables ($8f) and the overboost cutoff tonight and it won't let me enter a value higher than 10.61 psi (208.80 kpa). If I enter a higher value and save the scalor (is this the right term?) tunerpro automatically backs it down to 10.61 psi. Please tell me this isn't some maximum allowable value. The boost tables allow for more desired boost than that! And this turbo will make it too. I currently have drafted it to maxing out at 12.20 psi on the top end. If 10.61 it is some max overboost value, is there some way around it to allow higher boost?

208 kpa is around 16 PSIG, which will be the maximum that $8F is capable of reading, if not slightly lower at 200 kpa (around 14.7 psig), since it uses a 2 BAR MAP sensor. The 2 BAR MAP sensor will usually have a little buffer over the absolute 2 BAR limit, so this may be why the code will allow 208 kpa.

You may want to consider $59 which will allow up to 3 BAR (30 or so PSIG), but it does require the use of a 3 BAR MAP sensor, there's no 2 BAR MAP sensor setting. $59 will work in the '7730, '7749 and the '7727 along with the variants for these ECMs.
