Possible Plug and Play SC400/SC300 ECUs
Okay. I am talking to the ECU developer at AEM about standalone ECU solutions for the SC300/400. Can anybody tell me if the plugs for the SC300/400 match those of the Supra? If so then he can build a plug and play unit for the SC300 & 400 easily.

I wan gonna call AEM on Monday and ask the same thing...I saw an ad that they are plug-n-play for hondas and a few others, and I was wondering if they're the same as Supras. I'm gonna check the ecu diagrams from APEX'i that were for my s-afc, and I'll tell ya.
Update....I just checked, and yes, the plugs are the same. You use the same diagram to hook to the S-AFC on both cars....so it's the same ECU, minus some mods that were Supra specific.
How much are those AEM boxes anyway?

The Greddy E-Manage may be an alternative to the new Weapon R piggy back. It is only about $300 plus harness and software too, but its pretty new and I dont know anyone with it.

Excellent. I hope the SC400 ECUs are the same too. Does anybody know if it stayed the same all the way through production (98-00), or just the earlier years.

Pricing
Oh yeah.....they're gonna be around $2000 for whats currently being produced. I don't know if the Lexus stuff will be more (if it even happens) because of limited market, or what.

I thought the AEM piggybacks were going to be sub-$1000? For that price you can get a real standalone system.

yeah $2000 is a ripoff, you could buy a Haltech for that and have it installed and still have cash leftover
btw: SupraTTs and SC3s may have the same plugs but I'm 99% sure from lots of articles and statements by expert MKIV owners that the wiring diagrams are a lot different...
the non-turbo Supra and SC3 are supposed to be the same... not sure which you are referring to

Ya...the non-turbo Supras have the same wiring layout as the SC's.
The "majority" of wires between the Supra TT and the SC are the same. I.E. rpm sensor wires, tps, o2 sensors, power, AFM, etc. I doubt they would use different wires for other things, as that would confuse the production of the cars. Just my thought. I do know that for SC300/400, GS300 old bodystyle, MKIV Supra NA and Supra TT all use the exact same wiring diagram, same color wires, etc, to hook up a S-AFC. The Supra TT does use a different type of airflow signal. SC's have the Karmann Vortex AFM and Supra TT uses some sorta pressure signal thingy.
On that note, I'm thinking of switching over TO a MAF type sensor, since that allows for a TON more airflow than the stock AFM that the SC has. I can do that for only a few hundred bucks, and realize some gains of a standalone for cheap.

well thats not what the guy over in Hawaii selling the manual for the 2jz-ge to 2jz-gte engine swap said... he said the wiring is quite different...
but if he's wrong and AEM or whoever can develop a plug and play programmable ECU upgrade like the Apexi' Power-FC for $1500 or under, then I'm all over that like flies on ****
I need a simple but not too expensive ECU upgrade when I go turbo... conversions to Speed Density would be nice too; or at least compatibility with the SupraTT MAF... NA-Ts are choking from that pos AFM

As for the wiring...well you wire a S-AFC to a Supra TT using the exact same wires as on the SC and the Supra NA. I can't vouch for any wires OTHER than the ones used by the S-AFC....but those are the same...
