It doesn't have trans control built in, you need a Microsquirt (connected through CANBUS) to control a 4L80E.

 

 

I hope they fixed the issues with injector drivers on those things

 

 

There have been alot of issues on ms3 pro’s last year or two now. Injector drivers were failing and melting cars down when fuel delivery failed. I would go holley

 

 

I think it was like 5 units out of a few thousand, but still any number is unacceptable.

The Holley software is nice and easy to use, but doesn't have all of the features of the MS3 Pro, but not everyone needs all those features.

The MS3Pro module is like $800 and can fit inside a factory PCM case for a plug-n-play combo. It's all SMT electronics so it's more reliable than the v3.x based PCB's.

Do you have experience with Megasquirt?

I really like it, but it's flexibility sometimes causes confusion as it's a complex system. Most of the support forums expect you to be an advanced EFI user, so sometimes beginners don't get the level of help they need to be successful.

If you can be specific about the exact requirements you need or want we could probably give you some pros and cons. I.e sequential vs batch fire, what triggering system you use, etc.

I bought this for a turbo 4 cylinder- but haven't used it yet. He has a V8 version with cnp and knock.

I don't have the actual numbers, but I don't think it was that many vs production totals but it doesn't matter anyway.

But yeah, you are right, most people on here don't need any more than a stock '730. But in regards to performance, this place is dead and stuck in the ages. Most of my exposure to high tech builds is on facebook groups now.

Even the turbo forums are boring now.

So the choice was between a $2,500-3,000 setup by Holley or an $800-1000 setup that has (or at least can have the arguable ability) the same features and you went with the $3000 setup? Why?

 

 

I think your figures are a little off. If money isn't an issue for you or the Holley has some feature, convenience or warranty that MS didn't then that's fine but otherwise you might take a look again.

DIY AutoTune has the MS3Pro with the harness included for $1500 normally and they will frequently run 10% off making it $1350. I've seen it at 20% off on Black Friday I thought which would make it $1200. I found the MicroSquirt 4L80E controller at two websites that didn't say it was out of stock and allowed me to add it to the cart and go to the payment screen at checkout. Grab a blutooth connector (I can't recall but I know mine wasn't more than $50) and you can mate it to any android phone or tablet.
MS3 Pro $1500 at least $1200
Controller $500
Blutooth controller $50
Total roughly $1750-2050

The Dominator EFI $1700
Wiring harness $350
4L80E harness $177
Holley LCD dash $840
Total roughly $3067

 

 

Didn't mean to be disingenuous I just assumed with the Blutooth link you would just use a tablet and most people now-a-days have a tablet. If you aren't familiar with what it looks like on a tablet, here is one of the screens that mine uses:


I figured it had to be something like that. I know some guys that also only buy big name parts because they are building a show car and are looking to win big awards, didn't know if it was something like that either.

 

 

Yeah, Holley might be a better choice then.

 

I think it's time for MS4. The trans controller needs to be built into the main ECU. This is probably what hangs up a lot of people.

That, and when they realize they don't know how to tune they can just drop it off at a Holley shop.

I'm still running MS2 though and the car runs perfect.

It's my stock Corvette that keeps having PCM issues. GM electronics are junk lol.

I'd be interested in the ability to add the feature to a new ecm along with a VSS buffer OR an internal GPS feature. I think making the Transmission controller with harness standard would drive up the price by $300? maybe less? If you had a manual tranny it's something you wouldn't need either and that's been one of the big features of the MS Platform, being able to buy only what you require. Bare bones fuel only MS1 or shoot-the-moon MS3 Pro with a trans controller.

 

I see your point, it's definitely a 'modular' system where you buy what you need.
