I have a gang of megasquirts that all need to be repaired. Does anyone have a recommendation on a reputable source to help me with these?

2- 9093MS2 faulty map sensor or circuit
1- 9697MS2 faulty tps circuit
1- 9697MS2 unknown sync issue

Peter at pftuning.com has repaired a RaceCapture for me. He also works with megasquirt. He may be able to help.
Doesn’t diyautotune or ampefi offer repair?

diyautotune does offer repair services, I sent my mspnp2 to them last year because I was convinced there was an issue with my ECU. Want to say it was like $50 for initial diagnostics + additional cost depending on repair.

Not saying OP doesn't have issues w/ hardware, just relaying some personal experience here.

I've nearly sent an ECU or two back for repair. Before doing so I happen to figure out it is something I've done in the tune or something wrong with the basemap that was causing the issue. I'm looking at you 200deg hysteresis in the trubokitty CLT fan programable On/Off. I thought I had a broken something on the ECU that the fan would stay stuck on. Turns out whoever put that there meant to put 10 degrees swing which would be 200? Basically this is keeping the fan on till -10deg F. Maybe was playing with different on/off temps? idk. I've actually made this mistake in my own tuning, separate from the basemap download. Anyway, the point is check and doublecheck and keep trying before blaming hardware.

@Braineack This is in the 99-00 basemap on your site. I think it might be in others as well if you want to update them. Maybe this is how it used to be set in old firmware or TS with on/off temp instead of hysteresis, but this is how it loads on current TS builds from a fresh "Load Tune" session. Would like to know why if I'm missing something causing this. Thanks for everything on your site btw, amazingly useful.

weird, pretty sure its supposed to be "10" not 200. unsure how that's happened. no one else has complained about it or mentioned it ever after all these years.

Pretty sure you haven't heard about it is that it is unlikely used in your instructions. It is probably throwback to when fan control was done in MS2 with the Programmable outputs. Your MS3 instructions use a different output for fan, and in MS3 there is a Fan Control tab to set this.
The reason I'm using it is for a 2nd fan, using the programable outputs. I would have it come on 1deg later and shut off 1 deg later than the main fan to limit current draw and rpm droop. I didn't think much of it when setting it up this way initially and couldn't figure out why my 2nd fan would never shut off.
For your tunes I'd just set it to 5 or 10 for hysteresis, then probably turn it off entirely, then save out the tunes, if you are going to bother at all.
Just found it interesting that I ran into this a year or so ago.

no, that's what controls the main fan. I wire the a/c fan, INJ F, up to the fan control settings and check the fan on with with a/c option. This way the a/c fan operates with the a/c like OE, but the main fan is using the simplified programmable output in INJ G above.
