Be careful how hard it shifts you don’t want it breaking parts as well , and I doubt you will ever figure it out completely because there is too many shift schedules in it I’m headed to Bradenton to test my transmission out but I have tried it in the street somewhat and it’s beast mode I feel pretty confident it will perform as planned , by the way if anyone is in my area and wants to tag along let me know because 14 hours is a long trip
Great advice I think. Mike trained me not to exceed factory maximums, so for example if sport had the highest shift pressure then you could technically apply that pressure to perf and normal but you've never exceeded the factory setting technically. That's how I set mine up.....I basically did a lot of analysis and blended the various modes so they're basically all the same to take the variability out. Since I'm making a bit more mojo than a Demon or RE I also reviewed the torque mgmt during upshift the factory had in place and made some adjustments there as well. I've learned this will also help speed the shift.

Do any wires have to be cut on the factory harness to install the dual pump setup?

I'm hoping mine will last a little while. I've bumped shift pressures and it's shifting much more firm now. Maybe not needed at my power level, but better safe than sorry.

Now, someone needs to figure out when shift ID 28 and 29 are used. These are from a STOCK Redeye calibration! Found the same 6700 RPM shift points in the Demon cal as well. The conspiracy theorist in me wonders if there's some Easter egg deal like paddle down twice, paddle up twice, and hit the brake pedal for three seconds to enable these and that's how the Demon got the 9.65. In the Demon cal they're mapped to a manual paddle mode.

Those might be for launching the car with its "two-step" since you have to use paddles. Not sure.

It’s all on the tcm shift schedule tab. Just need to dig lil bit and you would find it

also, fuel cut off at 6500 for those cars.

Just have to address the fuel sensor wires, which is two connections.

I sell the tapped one now because it's plug and play and includes a filter. Had a lot of customers mess up installs on the injected kit because of the splicing needed. The injected one does now include the 285 pumps though just fyi.
