Anyone ever considered Megasquirt?

Christian, I was wondering if you were still using some of the idle devices in your new manifold. Did you rig up the Fast Idle valve, etc, or were you able to miraculously tune them out of the equation with the EMS?

All the IAC stuff is still present, you need it to keep the car idling. In fact I kept all the stock sensors for the manifold. Besides the IACV, nothing else on the intake manifold is needed to run the car with the EMS. EMS wont give you a CEL, its just stuff you may want to know, like intake & coolant temps.

My AEM boost sensor, now that's something I do need to keep installed

I take it you cut the rear of the upper intake plenum and welded it to the newly fab'ed one?

I've already looked at those for quite a while, and can't tell from the pics. I'll just ask you later via PM if I end up changing stuff around.

Looking for a little clarification.

I bought a 30-1002. The serial number is 1002-0134.

Correct one to use right?

Yes the old model is a 1002, the newer model is 1042. Dont ask me what the difference is, i dont know.

Sweet PM coming your way.

I think the new one is just smaller in size.

I got this from the instruction manual...

IMPORTANT information for customers already using the 30-1002 AEM EMS in their vehicle. The 30-1042 for the 91-94 NSX is a second generation design from AEM and incorporates knowledge gained from our earlier NSX EMS (30-1002). However, the 30-1002 and 30-1042 boxes are NOT interchangeable. They are NOT pin to pin compatible nor can the calibrations be freely swapped between the two. While both boxes are pin compatible with a stock NSX, the extra functions added to the 30-1042 necessitated a different pin out for the added features. If you have modified your wiring specifically for the 30-1002 and are now installing a 30-1042 then you MUST confirm that the extra wiring is still valid. Additionally, as this EMS is now a dedicated unit to the NSX, many internal allocations have been changed to yield a more logical operation. A 30-1002 generated calibration WILL NOT work properly in a 30-1042 without substantial modification.
The installation of the AEM ECU on the 1991-1994 Acura NSX uses the stock sensors and actuators. The base map is automatically installed in the base calibrations directory in the AEMPro directory on your computer. It is named 1042.V#.##.CAL.

Yes, that is what i have in mind once the project comes to an OK point and everything is running and working properly then i will go with AEM new NSX ECU, had other options in mind but cost more money or are more complicated to install and tune so is better to go with what is working for this engine and is made for it.
