Car ran great in closed loop was drivable Never drove in open loop. Now car stalls at random with key still on loses connectivity to tunerstudio at same time fuel pump stays grounded and running, with no rpm signal????

The run log posted doesn't show any rpm loss, got another log that does?

They all look the same. Car runs good then shuts off. I'll get a cold start it will be in cold loop and richer.

I have re flashed firmware and I reloaded tune. Also created new tune.

Looks like the ECU went offline completely, stopping the log. Are you able to duplicate the problem on the Stim, or does it just happen on the car?

Is this a regular Stim or JimStim?

Reg mega stim worked before

How do you have the switch by the RPM pot set?

Even if it's not getting RPM, can the MS2 go offline if on the Stim for a significant length of time?

new log

Went for a ride last night. It happened at lowes. Of course I left meter at home so I couldn't check for 5volts at tpi. I moved iat as its not mountedbto anything. Then took cap of wigled rotor and car started. I'm gonna look at iat sensor tobsee if its going to ground. Getting laptop battery or possibly new laptop to start auto tune and log this stuff. When driving out of the corner of my eye I see shift light come on every few minutes. It's a new distributor may warranty it.
Hate being a parts changer.

Bummer on the intermittent operation, but if it stays working on the stim, then its a wiring or noise interference problem, could be bad distributor connection or something else..... like all wiring problems..... 99% of them are bad or intermittent grounds.......Good luck

I figured so Matt gave me a what to do next if it happens again
Thanks
