Has anyone checked out the AEM plug and Play ECM? Part #Part #: 30-1220 On the AEM website. $2457.00 seems a little on the high side considering you have to have a injector driver to run the Low impedence injectors. I down loaded the latest software to take a look and must say I was impressed. It offers all the adjustablity anyone could want and work witht he factory harness as well as runs all the factory equipment. Just take out the factory PCM and install the AEM unit.
It has me thinking about unloading the GEN 7 DFI and going witht he AEM plug and Play. At $2500 its still cheaper than BS3 after you factor in trans control and theier guage add on adapter and such.
Just some info I thought I would pass on.

Alright, I am new to the LS1 croud. What's the difference between the 98 PCM vs the 99+ PCM's? Don't they all go off of 3 bar MAP sensors? If so, I would imagine they all could be tuned for FI well.
Heck my single bar MAP sensor in my LT1 is tuned like a champ and I'm running 16#'s of boost.

No one makes a tunning solution that will aloow you to use more than a 2 BAR MAP with a 98 PCM. You lose out on all the Real Time Tunning options 90% of the time as well. That is why most of the big runners with 98 model cars have repinned the PCM to be able to use the newer 99+PCM's or go to a full standalone like GEN 7, FAST, or BS3.
If thats the case, I would (and will plan to do down the road when I go FI on my 98) go with the newer 99+ PCM's. I have seen how easy it is to dial in perfectly a 3 bar MAP sensor car on high amounts of boost.
Im not a tuner nor will act like one. I just like to build cars and have an expert tune the car.
But whats out there that will allow you to keep stock gauges? AEM does I believe, but does BS3 or FAST?
Thanks

BS3 I belive has an adapter or add on, or something along those line that will allow you to keep the factory gauges. If I get rid of the GEN 7 DFI for another setup it will be the AEM plug and Play unit and one of their injector driver boxes. I have always had good luck with them on the mustangs I have done, and really like thier software.
the biggest draw back of the stock computer is simply put OBD2. That is the biggest advantage of after market ECUs. I have seen and really like hp tuners, 3 bar SD is what tunes my car.
I have seen and also like AEM. A couple of my good friends around here have GT47-88 powered supras so i have seen the software alot. The features that it provides is impressive, especially considering you just plug it in. I would like to see the set up in an f-body, but i think that if i was going after market i would want a computer to control my race car that i drive on the street.
Thats why if i replaced my ECU i would go with BS3 or a FAST system. IMO they have the features im looking for without all the unessacarry fluff.

Verdad Gallardo The only thing you have to have when going to AEM's plug and play is the injector driver to run the big injectors.
I have personaly used: HPTuners, EFI LIve with a RoadRunner, FAST, GEN 6 and & DFI, BS3, AEM, and Motec. Motec only once though. BS3 works awesome. GEN 6 i like until I used GEN 7 and I love it. HPT and EFI Live work well with the stock PCM. Motec was crazy. AEM is my over all favorite. When their plug and play box is released I will have it. Period. Its the only reson I am keeping my stock wiring harenns and guage cluster.

So BS3 or FAST wont allow you to keep your factory gauges? By saying the only reason your keeping your stock wiring harness and gauge cluster?
Coming from the supra world I know with AEM you can retain the factory gauges. Hince, plug n play

the 98 pcm has had it issues.. one is the false knock problem that was still present in my car until i got rid of the pcm! 
The 99+ have a "dual write" code, non singular, that is why you see most of the tuning handheld stuff for the 99's and nothing for the 98's. I went BS3 cause i needed plus 15psi, afr targeting boost control, 4l80e controller and stock gauges... and i just didn't want to deal with the 98pcm...
