Had a chance today to hit the dyno for a little fun. This time around with normal pump fuel but the BMS WMI kit activated running a single BM10 nozzle, 75% meth to water mix. Our Stinger is also equipped with a BMS prototype intake and BMS BOV kit.

Results were pretty impressive. I played around with some different boost, timing, and AFR levels, but power was pretty consistent in the 450-460range, best results came running a 75 additive on map8. Map8 allows adjustment of boost as a function of WMI flow with 0 being close to map1 performance levels and a 75 additive being close to map7 levels. The additive can be set up to 100 to exceed map7 levels. I tried some higher boost levels and while torque went up, peak power didn't improve much, and timing drops ticked up, so we're probably at an octane limit here. Next go around we'll have to test E30 + WMI.

Per usual we'll include the detailed datalog with our dyno, something the other Stinger tuners are afraid to do, because with the JB4 there is nothing to hide. With the JB4 you can always record look at your own data any time you want.
