When she met me I was a daily driving a 71 nova that I had built to match the death proof car as a joke. I drove that thing for a year with a th350 and somewhat deep reared. Dynoed at 275 at the wheels which isn't crazy but was quick. I don't understand how she can be surprised by any of this car ****.

I honestly think it is touchy because I am trying to keep it at low boost. It just doesn't want to do it and probably has super narrow parameters that you have to really test to get just right. Aidan spent 30 minutes doing pulls with me and we got it pretty close. The next day I got overboost. I have the low canister on it right now and it does 7 pounds. I am trying to tune at 170 kpa for the safety of my stock 150k block. The EFR just wants to do more. I spent some time trying to mess with boost by speed to see if I could tune it to waste gate for 1st and 2nd because here in the PNW with 205s it is a total **** show in the traction department. I didn't get it right and it just burned straight to overboost. I will figure it out but it was a bad *** eye opening experience of just how fast and far this ****** could go with ALLOFIT. Then tuning EBC will probably be much easier because you are just guiding the pissed of race horse and not trying to get it to trot.

Not exactly. It will hold ~150kpa just fine, with a bit of creep at the end. So ebc should have an easy time. Did you try raising the Delta like I suggested?

I did raise it I was still getting creep. I am going to mess with it more today. It is actually fun. I don't have any really nice open streets on my side of the river though. Mostly doing the onramp thing. I seem to be fighting issues with consistency.

With Boost control Speed table does is it just set the upper limit and anything below the upper limit reverts to the target table? Does my 94 even have a speed input back to the MS? When you set the table up do you want it at 0 kpa or 100 kpa? For example my table now is.
20MPH = 0 kpa
45 = 0
55 = 145
65 = 170
100 = 170
120 = 170
I suspect for this really to work well I need to figure out a ABS type sensor or something on a front wheel.

Your megasquirt has a speed input. It's really nasty. Cable might need to be lubed. Use boost by gear instead of boost by speed.
Look at your logs.
The cluster outputs a 0-5v square wave generated from the cable input. The megasquirt can read this.
Abs sensor is a VR signal that ranges in amplitude based on speed. You need a VR conditioner to take advantage of that. I currently have both front and rear abs sensors wired in so I can do differential wheel speed traction control

Good point. The roads are snot around here right now. I am tired of sliding around if I even remotely push the gas. I moved the delta way up and that did help. I am going to slowly bring it back down.

I don't have any creep at all when waste gate only. It holds 7 pounds every time without EBC. The creep happens when I hammer it in 3rd or 4th from a cruise as well. 4 to 5 k. But Delta turned way up did arrest it. I went from 20 to 35. I am going to dial it down slowly. I need to wait for dry pavement though. If anything the slightly delayed response is not a bad thing right now.

I am going to pick your brain at some point about all this. It is over my head a little now but it won't be some day.
