Default MS v3.0 Issue

So I just built my MS1 for my '90 and everything checks out visually. Only deviation from the standard build is the idle control. (kit from DIYautotune)
(Built with no jimstim btw)

Now heres my problem. I flashed the B&G Standard code and went to check out my readings in megatune after I rebooted w/o jumper. It seems to be showing crazy readings such as 7904 RPM, 22.0v battery, 74kPa engine pressure, and 43% duty cycle. (Engine off, just key to ign)

This cant be right, did I screw something up on my board?


Aside from that, after I flashed the Ms1 Extra 029y4 code then rebooted w/o the jumper im getting a constant clicking from what seems to be my IAC solenoid, the middle LED on MS is flashing in sync with the click. I get no connection in megatune when running this code.

I've searched all over but I cant find anything close to what im getting.

Well, first off you cannot use the "standard" B&G code. I don't mean you shouldn't, I mean it doesn't support spark.

(there's a reason that MSnS-E isn't just called MS-E)

So focus on either MSnS-E build 029(x), or MSnS-HR build 10G or better.


The clicking and flashing kinda sounds to me like the unit is resetting itself constantly. Is it possible that the flash was interrupted or the code somehow corrupted? I can't really think of where to start here other than telling you to download a fresh copy of the code and try re-flashing it again. Don't bother with Easytherm yet, just a raw distro.

Could be a sign of a config error:

Reflashed MSnS-E build 029y4 and I still get the flashing middle LED and the clicking from my engine bay. Still no connection in MT.

I opened the mini terminal in MT and turned on MS and got nothing on screen from the MS. Just a blank terminal. COM/baud are both set correctly.

If it is an output conflict, should I start disconnecting output wires on my harness to see if it alleviates my problem?

Please post a copy of your MSQ and a data log of the clicking behavior.
