Map ECU2 vs AEM FIC?
Before anyone says search, I already did, and didn't find anything useful.
I have a 99SC300 (vvti, OBD2) than I am going to turbo. I am just trying to find folks who have had experience with this particular setup using either unit. How difficult was your install/setup/tune? How much power are you making? Do you regret getting x unit; if so why?
TIA

I wish I had an answere foryou but from what I've seen with many new(er) parts out there, not many people have information on them. You just have to be the one to bite the bullet and go for it or wait a year until someone has posotive or negative experiences. Both sound like great units, probably can't go wrong with either one since they are both proven companies. Best of luck and on a side note, if you go with one of those units, be that guy that posts a usefull write up on thier experience with either management.

the FIC is designed to work with 0-5v airflow signals which includes MAP and MAF. The KVF system in OBD1 cars will not work with it.
Its not restricted to OBD2, just MAF or MAP (which are analog signals vs the digital KVF)
Both units, tuning-wise, are pretty close. But the FIC is MUCH cheaper, and the MAPECU2 can do a KVF/MAF to MAP conversion.

Check out this thread, http://www.clubna-t.com/forums/showthread.php?t=5819 the owner has a 99 sc300 w/ a FIC.
I've read that the FIC is designed to work with OBD2.

Thanks for all the help so far, guys. I am really enjoying my time as a new Lex owner!

I am an AEM distributor/cert tuner and use a ton of their products everyday on customers' cars, but I am disheartened with the FIC. I was very excited when it came out because we do a lot of non turbo to turbo conversions, and that is what the FIC is designed for. Their way of intercepting the injectors after the ECU is great, as is their idea of adjusting timing by simultaneously delaying the crank/cam sensor input.
However, here are the issues: The two connectors on them are **** poor quality wise. The pins of the first four units I have have fallen out or broken their clips. Two units had wires in the wrong spots in the harness, and AEM didn't have much to say about it other than, "well then switch them". Lastly, two out of four units have had to go back to AEM (customers were not all that excited about that lol their cars sat waiting) for repairs/"upgrades".
Once they get working, which they do as long as your car doens't require an injector kickback signal (like all newer toyota's, scions, etc). In that case, you need to hardwire in two 1amp 50v. diodes to not confuse the FIC. The logging is ok, though the software is very glitchy and the z110. code freezes the unit (which you have to send to AEM to reset).
The map 2 ecu is a lot more expensive, but lets you eliminate the MAF, which is a huge advantage, and is easier to wire and more reliable. We also know that it works on our cars, and the logging is a lot better. It has some limitations and the interface is mediocre, but it works. It lacks the power and resolution of a sophisticated stand alone, which is apparent to sensitive driver, but is very good as piggybacks get.

Ian, THANK YOU. That is exactly the kind of feedback I was looking for. I think I had seen you post about the connector quality before, so it is good to get confirmation. That has always been my deal with AEM: great ideas and products, but their QC SUCKS. I personally know of 5 cars killed by defective ECUs, and AFAIK their CDI box STILL doesn't work reliably. So I take it that the map ecu2 would be your choice? I see you are in Cali; can you speak to emissions testing at all?
Thanks,
Kurt

Use the map 2. We've had a chance to try the FIC on a few more cars with little luck. Generally, it works very well for adjusting WOT fuel, but causes an amazing amount of stutter/misfire/tip in issues with multiple pulse enrichment injection motors, which most of the newer cars are.

map ecu2 is better than fic from my experience in all the swaps i've done i'm a tuner and a fabricator as well fic is a pos... if your gonna use aem go the aem ems...... not the fic...
