Yeah - blowing fuses is very unlikely to be software. Got to find out what's going on there before you break something

This is what you're asking for?

I'm scratching my head about this one. The only wires he ever touched today had to do with the LC1 WB. I don't recall either of us ever going close to the MS harness. We disconnected the cops to do the aluminum sheet install. I have to say that the only other thing he did was open the Idle page and change some settings there. I guess he burned the new ones to the MS and my guess is that I'm having problems with that particular part of the MS

This is strange. Your MS doesn't even have control of the idle so I don't know what settings he has been messing with. The only settings he could change to mess with anything during idle is your fuel and spark. I'll check out your msq.

I almost forgot; before losing communication with the MS the first time I got some resets on the MS as I was watching the screen. I know it's fine still. If I were to put another ignition fuse it would connect again. I just don't want to do that just yet (for one it's night here and second, I don't want to press my luck).

I have to speculate that this is similar to the last time but the cops held up this time. Maybe we're burning some files to the MS we shouldn't be burning to it?

****, this makes me feel like a moron!

I really don't see how just software would cause issues. Do you have the current limiting resistors in?

Either way, one thing makes sense - run it off a stim, check the current. If it's drawing a lot of current when alone, something is shorted on the MS. If its drawing it only when plugged into the car, then it's something in the car's wiring. If it's been reseting, my guess is maybe it's the power wire to the MS, or a short in the case - like a loose wire shorting to the body of the MS inside.

If it's none of that, next I'm look at measuring the resistance across the fuel injection lines and the ignition lines, and see if there's a short there.

The only way to do this stuff if you can't think of something obvious is systematically, or you'll repeat yourself a lot, and get frustrated.

I built his MS. He doesn't have a stim to hook anything up. Though it was all built correctly and ran my own car without issues for a good amount of time. Plus he has been using it for a while without problems. Besides the idle issue he spoke of when turning on A/C, even though that doesn't have much to do with MS considering idle is left to his stock ECU. Engine wiring or something similar is what I'm thinking, though it's hard to troubleshoot someone elses wiring job when you have no idea what is going on there.

Yeah - then that would be my guess as well. Something "magically" coming lose inside the case is a long shot. Something magically coming loose in the boomslang is a possibility since it seems more physical abuse - and wiring in other places is also very likely. If it was just not starting, I would wonder about a sensor line, but it seems like some power is going through there to blow a fuse.

The only wires we touched had to to do with the LC1. We were having trouble having the MS read AFRs and thought that the LC1 O2 sensor had gone bad. Those are at the driver's feet. Any mess in the wiring harnesses must be at that location. That could be it. I'll see if I can find anything. I'm going to disconnect the MS just in case (lost communication with it yesterday anyways).

Thanks

The LC-1 does have a power resistor in it, and can flow a few amps. And it has two grounds, if one got weird and touched the switched power from the ecu that would do it.

Anyway, too much theory, not enough checking. :-)

I put a 20amp fuse there this morning and voila! no more issues. I think it did have to do with the LC-1. Before that it wasn't properly connected. Now the MS is reading it perfectly but the gauge in the pod is reading it backwards

I guess I have issues with that harness. I'll have to have it thoroughly checked. Thanks for all the help.

BTW, when is the DIY autotune MSPNP going to come out for 96/97? I got no clue about Maps. Everytime I mess with some map I get it wrong.

At least my car is back working and I finally secured the cops.

This MS thing is not for seniors. :gay:

Someone should give you a map!! At least as a starting point. Then look it over, sometimes just cause someone is using them doens't mean they aren't weird.


Checking the harness is tedious but not difficult, something you could do yourself. Take a lot of notes, make up a spreadsheet, etc. But it should be something you can do and give you both a little peace of mind and a oneness between horse and rider.

Lol Abe, the only thing is I'm not sure whether at this moment I'm the jockey or the ***! haha

Thanks and yeah I want a map (there is no smilie with a crying baby).

The MSQ is he running is the one i made. It utilizes many of the same settings I use because we have the same injectors and motor. So most things are close. The other settings are from the DIYautotune map and are standard from miata to miata.

I get that Chad, but Cristian already fooled around some with your original settings so now I can't compare with the ones I had. He changed the spark settings and the VE table.

At least now I can see the real AFRs in my MS. I just went out for a short drive and I'm seeing 12s while in boost so it's cool.

Thanks,

Rafa

Yeah; go figure Magna. Happy 2008! Missed you man! :gay:

Next thing is to re-read Joe's thread on how to install a WI tank; find one more intelligent than me to do the install and I'll be wet! Almost forgot, I first have to buy the kit from WOT. If I buy any other he might just kill me.

Got it Chad, I'll email you my last datalog.

I suggest a SOLID four hours with one set up before further changing it. Really, any new system will have a lot of teething problems. Get used to it, see what works. Then add water.

Also, run your intake filter under the passenger seat. Then, when your rider wets him/herself, you get controlled intake temps.

Ok guys, first of all thanks for all the help. My car is finally running quite well.

Here's my latest datalog.
