I'll give that a try tomorrow and see what I can find out. I just opened the laptop to see what it's at. Currently set at 0. Hopefully that's the issue so I can return the msd. I'll post results tomorrow. Anything else I should check while I'm at it? You seem to be the MS guru around here.Your not blowing spark out unless your running 15psi or more. If the car is breaking up at 4k rpm you should be checking spark hardware latency to ensure it's not retarding timing with rpm.
If you do install the msd this latency issue tends to get even worse. Lock the timing at 20* and rev the engine to 5k and hold while strobing the timing, does it retsrd with rpm? If it does bump the latency up by 10, I have had to run these as much as 210microseconds.
The microsquirt can simply fire the msd directly over the white wire or you can install it in the traditional way and let the tfi trigger the msd. Both will work, increase the spark duty to 75% with the msd box. The grey tfi used in our cars has no dwell control from the eec so if they are attempting to do so it will overheat the tfi and cause spark issues as well.
Let me know if you need anything else, I do remote tunes.
I have a new set of ngk v power tkr6e's in the garage. Think those will work too?Set plug gap at 32 run either a 3924 or 104 autolite copper plug, no platinum or other fancy stuff.
Post the tune if you would like a sanity check.
Replying to your first and second reply. Yes Ford lu47 injectors. Stock cam, stock long block with valve springs & head studs. That's pretty interesting how many issues you found. I compared my tune to the one the tuner made while he had it on the dyno (which is the one I sent you & the one loaded on the micro) and he didn't change much except smooth out the fuel table a little bit and change idle. He also changed a couple things in idle control. I was a little surprised by how much he didn't change because it didn't run that great. It starts in about 3-4 seconds and idles around 875-1000 rpms. and I need to feather the throttle on hot starts until it stabilizes itself. I guess my next question is what's your price to build me a tune?Oh and your Accel enrichment settings are... interesting. the end PW should be 0 or this will create a false rich condition for both accel and decel events. the TPS curve does not make sense it decreases with throttle delta.. ie.. its adding more fuel with less throttle movement speed.
My conclusion: I will refrain from comment. Hopefully I am wrong

stock cam should idle nicely at 750 all day. We can likely get this thing worked out in a few hours road tuning with a hot spot.
Okay. I'm going to get the spark hardware latency dialed in an hour or so. Then we can go from there.Please refer to my services page for pricing [in my signature] or you can email me at blackfoxefi@gmail.com

Thanks I'll put those in too. What would your next move be? Closed loop idle?You said you need the injector data for the LU47
Deadtime- .905
battery correction- .129
I have. Im going to watch them again while Im working on it too. When I think it's okay I'll send a datalog and the current tune.yes it would. you should watch my videos if you have not already
I use 0.901 with the same injectors. Close enough.You said you need the injector data for the LU47
