ECU Options for Automatic Owners
I think we have all come to the realization that auto trans owners truly have the short end of the stick when it comes to modifying their cars. This is why we sat down and started figuring out how to install an engine management system that would keep the "HOLD" feature functional.
What we have come up with is an adapter harness that allows installation of multiple EMS systems while keeping the stock ECU operational to control the trans computer. The stock ecu piggybacks on the the EMS signals with just enough inputs to keep it on "life support".
We are still in the testing stages, the R&D has been done, but we need to try a few more configurations before offering it to the public. I figured I would start seeing if there is going to be any interest in the adapter beyond our few customers.
Below are pictures showing the adapter with a Power FC. However, we designed it to be able to be used with any plug and play EMS system, such as the AEM, or even the reflashed ECUs like the Pettit or M2.
Your input or interest is welcome.

sign me up. I'm glad I didn't toss my stock ECU.
although I don't really miss my hold feature that much, this is something taht would give a lot of us auto owners a better piece of mind.

Yes, its good that someone is paying attention to the auto guys! It's a wonder we don't have to go around saying unclean, unclean! I do know those adapter plugs are very expensive so..........., I think the cost will be the biggest factor on this set up.

It will be available once we have completed testing on a 94 automatic. We have a customer that has agreed to let us use his car for the installation. We just want to make sure that there are not any issues on the 94-95 that are not present on the 93.

The harnesses will not be for sale until after we have finished our testing, the price is going to be $275 , which will include Priority Mail shipping anywhere in the US.
Do the PFC and the Stock ECU fit together behind the kick panel or do you have to relocate one?
I'll take one - its for a 93 soooo I don't care if it works for a 94 or 95. PM Me.

We have not gone into production on the harnesses yet. We need to verify that is will work on both, we are confident that it will, but we need to make sure. We will let everyone know as soon as they become available.
Yes the PFC installs right next to the stock ECU, just have to remove the top mounting bracket.

What you can do is email sales@banzai-racing.com with the title "FD Auto Adapter" and we will send you an email letting you know when the release date is, this will basically hold you a place in line so you do not have to wait.
I've hooked a PFC up to an automatic car before and realized very quickly that there is MORE that is lost than just the hold function. The transmission will not downshift properly and I suspect that the torque converter does not lockup properly as well. Sure you can drive around - but the transmission performs like ****.
Question: Should this setup cure all of the above drivability problems in addition to the lost hold function?
