I am looking to upgrade swap out my factory ecm for an aftermarket ecu. I have some experience with the Holley commander 950 since that is what my brother used in his Monty Carlo SS. I do plan on driving this on the interstate so I would need to keep the lockup functional and also cruse control, and would like to be able to use my factory wiring either repining it or using an adaptor. I am having alot of trouble of tuning my stock ecm with either the ecm not responding, the auto prom not responding or able to emulate, and or tuner pro rt completely locking up on several different laptops and different auto prom units. I wasted 1 year trying to figure this out and I am tired of messing with this. My experience with the Holley 950 is it was very easy to tune, almost to easy. It told you with a red box on which cell of the table it was using and if you needed to change anything you just go to that cell and edit it. Are other brands this easy to tune?? Does any other brand have TCC clutch control and the ability to use the factory wiring????

If your using a '165 ECM you may be interested in http://www.thirdgen.org/techboard/df...asquirtii.html (NEW adapter board for megasquirtII to 86-88 tpi cars)

It allow MS to plug directly into the factory harness and will handle TCC based on engine rpm/MAP.

Also if you can buy a pre-built & tested Megasquirt from DIYAutotune.

I looked and I can't make sense of exactly what I would be looking for. I plan on using the factory harness, from the sounds of it the adapter is not out yet. What would all the parts for the megasquirt II would I need?

In addition to the bare board there are about $20 worth of parts to be bought from Digikey. All the parts and assembly instructions are on the web page with the adapter board.

Plus

Not assembled MS2 kit - specify NO CASE

OR

Fully assembled MS2

If you order a pre-built unit specify "NO CASE" as you would use the stock GM ECM case.

Plus a junkyard '747/746 ECM << this is for the mating harness connector and the case. After the connector is removed from the GM board the rest of the GM electronics ends up in the round file.

the problem is that i have ordered this adapter over 2 weeks ago, when i recieved it, it was TBI one, i was promiced to recieve proper one ASAP but it is still not here and i'm wondering if it even exist!

regards

Justin from DIYautotune just contacted me and confirmed that it was sent on 28th of May, now i know it is not their fault and they done their work best thay could and gave all support
so You can order MSII + adapter as easyest and quickest way to fine tune Your car

regards

BTW now i need to go to delivery company and customs and find a guy taht still keeps my adapter and kill him

EBL with the port mod hands down. plugs directly into your stock harness. Ask RBob.
