I skimmed through a lot of this thread as well as reading many posts more closely, there was some talk of 1JZ ECU's, has any testing/development been done on the JZA70 ECU at all?

I have read the whole thread now. Good to know there is a solid answer with the Lex meter. Although my car runs and idles very well.

Just asymmetric reply from crazy Russians ::flame::
Tests for 42-pin version now.
Sorry folks. I've been overloaded for a while now, but need to get that build of boards finished.
JZX100 ECU test. 3 boards running 68pin denso MCUs from external RAM. 540cc injectors from Toyota Caldina. No MAF. Engine tends to stall.

When you get around to it...how hard would it be to switch from 550cc injectors to 680 or larger? After you produce the modified PCM.
There's a "magic" constant exist in the code. Works similar to the "req fuel" constant in mega$quirt.
JZX90, 1JZ-GTE, MAP-based, also has this constant and could be tuned up to 850cc injectors. Maybe even more.

7M-GTE code (gray connectors) for IDA with some comments

I'm currently working on the replacement of a Karmann vortex type AFM with a "hot-wire" one from JZX100.
Also, I'm planning to replace altimeter MAP with a MPXH6400. It is strange that internal altimeter MAP has such a priority along with other ADC channels. Although the altimeter MAP has lots of pins, only three of them are actually used.

I've made experimental ECU with stock AFM, equipped with my external memory module + upgrade of the MCU (7433->5B25CT-1, which has +100 bytes of RAM).
Changes that were made:
1) Stock barometer MAP became external; can be easily replaced by an MPXH6400 (20kPa - 400 kPa)
2) A communication port with a bluetooth module / USB-RS232TTL for comms/firmware upgrade was attached
3) 5-pin connector was attached for an external hot-wire AFM (5 signals: +B, VG, THA, E2, EVG); ADC6 was used for this through 47nF/2k7 RC-filter
Stock code will be modified so that I will be able to record logs for MAP/hot-wire AFM to replace karmann vortex AFM either to a hot-wire type or to MAP.

I guess it's not dead.
I know beta testers (I'm one of them) are not as acive as before. Personaly I've spun a bearing and no time/money/bravoure to repair yet.
