Anyone have experience with AEM infinity?

Hey everyone,

I am in the midst of the slow process of building my m52 turbo street/weekend warrior car. I think at this point I have decided I want to go full standalone as honestly trying to find information on tuning the ms41.1 ecu is like pulling teeth, and being honest with myself, I don't want o learn how to read the coding used to get it all to work. I don't have the time for that with as much travel for work I do...

I have been looking around for standalone's, and megasquirt would be the first obvious choice. THey are supposedly coming out with an OBD2 pnp unit soon as they just released their obd1 version. The cost is pretty much right around the AEM infinity 506 unit, and from what I can tell the infinity is going to be easier to tune using volumetric efficiencies, and being that my build will be ever progressing, it seems like a great way to go as it will be better able to adapt to changes.

Problem #1-There is no pnp harness, so I will have to wire my own. The question in that is, is it worth splicing it into the stock harness, or at this point am I just better off isolation the non motor parts of the harness and wiring up jus the motor to the ecu? The car is gutted at this point, I am deleting A/C, pulled factory radio, no headliner, etc. It's going to stay a stripped down car as well for reference.

Problem #2-Not really a problem so much, but does anyone have any experience with these units? I can only find info on people running these on s54's at this point really.

Thanks in advance for any info.

Aem infinity are suspossed to be pretty good, ive never tuned with it other then just poking around with the software. Id recomend checking out haltech, super nice and easy software to learn on. In my opinion the only plus side to megasquirt is the mass of people that use them in e30's and well there cheap but you get what you pay for. Haltech, link, motec, and aem are all good choices put prices vary of course, not sure if any have a plug in play but it should be pretty easy to repin the factory harness to a different connector for any standalone.

I think after some more searching is what I may do is take either the ms41.1 dme I have and basically gut it for the connector, install the coil drivers in it, and wire that to the plug and pin kit AEM sells for the infinity. That way I wont have to cut up my harness other then for splicing in the c101 for the body side. I think this may be the least fragile way of doing this. From what I can gather, all of the sensors can be left stock as AEM has a profile for a '95 m3, so I would just need a map sensor to go along with it and I think I should be good.
