Can you ask them about running the AEM output to the Hydra in place of using the garbage onboard controller? That onboard controller is likely the #1 failure of those stupid ecus. I wouldn't pay a single dime to repair it if you had the option to just not use it and its expensive sensors.

Being able to NOT use that thing was one of THE big upgrades to the 2.7.

Can you give me more info on how to do that? Point me to a thread or link? This might be a good fix.

There's a bunch more out there, and/or FM should just be able to tell you how to do it.

Great info to have guys, really helpful.

Paul,

MS3. You know that is the answer. I don't know why you are still avoiding the inevitable.

I think that I'm avoiding it for two reasons.
1. The Hydra has been great until this. The car is running very well, but showing extremely rich on the AEM gauge. Plugs look about perfect. It might be a simple fix.
2. More importantly, I hesitate to start with a new platform and go thru the install. I can't do it by myself ( I bungle small electrical connections ). If I could find a plug and play and someone to kind of hold my hand, I'd make the switch. It's not a $ thing, it's about having the right person to advise and help. I've been asking around my area for a guru who can help out.

My new engine is at about 400 miles right now and, according to gas mileage, using about 10-15% more fuel than the old one. Changing oil at 50, 500 and 1000 miles, so even if I'm a little rich, there shouldn't be any harm done. After the 1000 mile mark, I think that I'll be ready to make the move. Any recommendations on a resource to do the work? DIY Autotune for the MS?

It might be helpful. I had pretty much decided to move to an MS, but if the seller is reasonable....
Thanks for making the connection. How about a positive cat?

Paul

Agreed to a price with the seller, paid him and he already shipped the Hydra. I have my fingers crossed, but will be out of town for 6 weeks or so and will install in late August.
Thanks DNMakinson

Hope it works.

And, yes, I work for PosCats.
