my buddy has an MSM and can't get spark to work. He paid a guy $1000+ to set it all up, and the guy can't make it happen. Anywhere I can direct him?

If you have a boomslang harness (or wired yourself all the signals) I think you have to disconnect the Crank angle signal AND the Cam angle signal. (and keep them disconnected for ever, you can't use them)
Worked on a NB Facelift '01+.

If you use a grinded clip you can open the connector C, lift the small plastic wing and pull away the pins without cutting the wires.
They are the pin 33 and 39 on connector C

so you're disconnecting the crank and cam sensors to the factory ecm, and only running them to the EMU?

 

Other way around. Get 'em off the EMU and leave them running only to the stock ECU.

NBs in general have always seemed problematic, and I don't know why that is. But for starters, follow the advice of jhoexp and musanovic, and disconnect the CKP/CMP wires from the EMU.

In order to be of much further help, details on the wiring are going to be needed. IOW- a complete and specific list of exactly which wires have been cut, which ones have been spliced/teed, and where they all go. Also, a complete list of the current jumper settings, a .EM2 file, and a .LG2 file with commentary.

I really hope this isn't a boomslang- those damn things use the same color wire for every connection and don't come with any pinout documentation so far as I can tell.


BTW- $1000 to install and tune an EMU? Damn, I'm in the wrong line of work.

 

yeah, this guy doesn't know all that. He's fucked. I told him to just run stand alone, then throw the stock computer and MAF back in for inspections.

Its over $1000, and they can't get it to work.

 

Did he actually pay someone $1000 to not make his EMU work, or is that what they would have charged him if they had gotten it to work?

 

If this is really the case tell your friend to give me 1000 dollars and I'll not finish the job too.

 

Not really sure. I know he gave the guy tons of money for it, and now wants it back.

I don't know how these piggy backs work...so back to the MS forum.

 

No, follow the connecting diagram on emu manual, but don't connect the crank angle and cam angle signals to the emu. (They should be used to monitor timing, but this function does not seem to work on NBs)

Boomslang harness may be expensive, but is made really well...with that the installation is plag & play, except for this 2 wires to cut on NB Facelift.

 

www.mazda-speed.com direct him there

 

Don't bother directing him there. No one there uses the EMU and are affraid to try anything other than an Xede or Hydra. One of the reasons I found this site is because I wanted to try the EMU and I was looking for someone that may have knowledge of it running one on an MSM. I just picked one up a few days ago along with a boomslang harness which is on the way.

 

I just bought an EMU and boomslang harness, hasn't arrive yet. My question is, does the guys EMU not work at all or just these two functions?

Also, the people that posted potential solutions, are you running an EMU on an MSM?

 

i am running it on a 01 not msm. works great.

 

You had to disable the two signal wires discussed above for yours to work properly?

 

yes i did disable them.

 

is this problem only on the 01+ or does that include the 99-00 crowd

 

There are preset parameters in the emanage software for the 99 engines, so I would imaging it's not a problem. If you disable the cam and crank angle sensors from the EMU, soes this mean you don't have the ability to adjust timeing?

 

The problem is only on 01+, the 99-00 works perfectly.

Msydnor, you can still advance and retard timing with cam and crank signal disconnected...they should be used just to monitor (and log) timing.
