Had some successes and some failures this week. My front brakes(here we are again) locked up and stranded me about 5 miles from the house. Had to have my son come with tools and disconnected the front. One thing I will say is nice about having the dual master set up. So I pulled it and put the old .75 back in and bleed and bleed and bleed. I swear these GM calipers have a pocket in the casting above the bleeder. I jacked up the car and put my bottle with the bleeder tube a foot above the caliper. Not till then did I start to get real amounts of air out. Now I have pedals like a rock, just crazy. I should have known the GM would be cheap on money but eat the ass out of your schedule. The end of the story is I have brakes. Actually pretty nice too, Shocked the hell out of me. The front end even moves down when you nail them. I took out the 2psi residual valves. I really think they were working against me. I found out these Fiero spindles will fit C4 rotors and calipers with an adapter plate. I think that,s the upgrade. I haven't looked at cost, may be a winter upgrade. I'll live with this for now.

The success was with Megasquirt. I ventured into the closed loop idle quagmire. It actually went well. A quick 10 min drive yesterday and it went well. Starts up and nails 1200 rpm, settles in at 850 just like its supposed to do. It almost came close to stalling 1 time. It ran down to 500 rpm but it caught itself and came back. That the one thing I need to hit. Would be nice to see it recover faster. I have to find that setting. EGO control I have the PID so its running between 13.4-14, 14 being the target at idle. Rpm target is 850 that runs 830-875. Really nice. I'm thinking auto tune for a little while, run the VE analyzer, shape up the fuel table and hit accel enrich. I have that about 2/3 done from running open loop so it should not take much. Pretty much ready to run the hell out of this season, Maybe do the rear tires in. My buddy just got back from a road trip so paint should be soon. I'm next on his project list.

Hey Steve, what are your PID settings? If you want a faster response increase the "proportional" value...just a little at a time please...pretty easy to send the whole thing into oscillations.

V3.4.3 firmware has been available for quite some time.

If you haven't,
It is important to establish a rock solid open loop idle before venturing into closed loop land.
Don't try to idle it at 14.7 unless it is happy there.

I just did an update. You're saying this isn't current, Darn it.
In open loop it was great. I could run it really nice 13.5-14.

Bent wrench. Now the car won't start. Is there a glitch in this firmware?

No glitches, perhaps your calibrations were not saved. This happens sometimes, not sure why.
Double check all calibrations in the Tools drop down menu

I found it. I had the wrong Microsquirt. Too many choices. It came back with 1 Tach out error. Found that and it started right up. I’ve never had the problem in the past.

I hope everyone is having an enjoyable summer.

I'm considering the car tuned. So much help from JPSEuropa. It runs so well and pulls so hard it's almost unbelievable. I'll need stickier tires at some point, these rears won't last long. I need to pull a couple 0-60 now. My best on the old spark map was 6.98 in 348ft. IDK controlling the power to the rear end on launch is going to be tricky. It comes up in RPM fast, not much time to it second and there is a nice solid squawk hitting second, pretty cool actually. With the new rear end, I don't think I'll see 5's, would be nice but I have my doubts.

I recently came across 1 (only one) C4 caliper on my shelf. Don't ask how- long story. If you want it- just pay for the shipping cost from Lake Geneva, WI and its your!

Can’t pass up that deal. I may be down to Racine in a couple weeks. I can pick it up from you. If something falls through I will pay to ship it. Sounded like a good reason to run out to LG.

Glad to help! Now I need to deal with my own car issues. The Seven is running great and my kid and his wife keep swiping it, so everytime I want to take it out, its gone . So the Europa is dead in the garage, but I am still not sure why it wont start. Have fixed one wiring issue, but that did not get it started
