Microtech lt10 help

[protege94 P.R]

Maybe you can help me I need the wiring diagram for install a lt10s on my Bg. Will appreciate your help Thanks

Well I figured out what my problem was. I flipped crank position and cam position wires off the miata cas to the microtech. The car idles nicely now and revs with some hesitation, but I'm guessing that is fuel related. Thanks again for the help. Later.

Looking at the settings for the CAS looks like that is OK. Your car starts so I think the ECU is getting the trigger signal.

But I am not sure about the cops. I think for the COPS the SparkTrig should be +POS because I think the COPS should fire when they receive the signal from the ECU. Again I am not sure about that you have to double check that to prevent to fry the coils. Also check the dwell settings for those COPS

My setup when I run Microtech in the past I use the stock dizzy and single coil without problems. Later I upgrade the ignition with four OEM coils and the X4 box again with no problems.

If you still have the stock dizzy, module and coil I suggest to wire that to see if there any difference.

Unfortunately with the Microtech you can not save the tune in a file. That is one of the major limitations of that ECU. Otherwise works great.

When I go into the microtech settings, I only see one setting for dwell. The Miata cop write-up on that site says to dwell them at 3.5 ms cranking and 2.5 ms at 12v. Any idea where/what to set the dwell for this? Thanks again. You have been a lot of help.

Im running toyota coil on plugs with built-in igniters with the Miata CAS. I'm copying the setup from here.

If you look at that website, I have my car wired like the "1.8L '95.5+ Schematics" I have the corresponding cylinder ignition outputs wired up to each cylinder's specific trigger leads.

In the Microtech software, I'm still using the input trigger of neg, and I set the output trigger as neg also even though it says twin.

When i get it idling, im seeing a 15 hg of vacuum so i tend to think that the map that's built into the microtech is ok.

Can you explain me your setup? You mention toyota cops. How do you wire it? Wasted COP setup?

Probably the MAP sensor is bad, problems with the firing order? If you play with the CAS back and forth do you notice any difference?

Playing with the Mixtrm should make a big difference if there is a fueling problem.

After playing around with settings including the mixtrm option in both + and - values, I've gotten it to idle at about 400 rpm (sounds lobey as hell like it has a wicked cam in it lol) if there is no load on it. If I apply any throttle, it doesn't rev up and falls on its face. I have tried to increase rpms with the idle bypass screw but if i turn either way, it stumbles and then dies.

I checked timing with a timing light and it seems really close to 10 btdc with how the miata CAS is positioned. I have pulled each of the toyota COPs and each of them have spark while cranking.

It seems like it wants to run, just something is holding it back.

Try the option MixTrm and play with it up or down. With that you can check if your need more or less fuel.

The LT10 was setup to run the Miata/MX5 CAS which is in the car right now. I'm currently at the point where I'm getting spark and fuel, and it sounds like it wants to run but it either cranks and falls on it face or stumbles for a few seconds and dies. Giving throttle just kills it even faster.

I found a collection of screenshots from another post that was a base bpt setup with 880CC injectors. I tried turning down the settings for Idle, Load, RPMWOT, and RPMCRS and nothing I do seems to make any real changes. Everything is stock gtx bpt parts except a walbro 255 in the tank.

Any help would be appreciated. Thanks.

What problems do you have?

I used Microtech Lt10 in my last built and works great

First you have to make sure that the Microtech is configured to use the stock dizzy or the trigger that you will use.

Hey guys,

I was wondering if anyone on here is running a microtech lt10 on their bpt setup. Somehow, someway the base map got erased on mine and I really don't want to send the damn thing back to Australia. Anyone who can help me out (especially in the Wisconsin/Illinois area) would be greatly appreciated. Thanks again.
