be hard pressed to get any replies, a very rare ecu, personally I've never even heard off it, have you tried doing a search or you could try googling it

As with most MR2 Turbo upgrade ECU's they are all factory set with Rom Chips (Which really can only be upgraded by sending tham back to factory).

SARD probably won't talk to you as is the case with most Japanese companies.

You'll find the sard ecu has a dfferent map with removed limiters, upper rev limit, increased boost limit, etc.. Unknown as to the current state of tune tho..

Pop it on and chuck the car on the rollers i say.. see if its good or bad.

Did a quick Google and came up with an Australian forum.

I'm pretty sure the Sard ECU will be a stock ECU fitted with Techtom daughterboards to allow the factory code to be modded. Techtom are a Jap company who manufacture the boards and Sard buy them and fit them to an ECU, tune them and then stick a Sard sticker on the ECU.

The rev3 ECU has two 64pin MCU chips containing the main program code which is why you usually need two boards (or a different MCU and a board) to have full control over the tuning.

The modded code will live in a regular EPROM chip plugged into a socket meaning the maps/code can only be changed by unplugging a chip and swapping it for a revised chip. The contents of the EPROM will be scrambled by Sard although the scrambling is fairly basic. However, this does mean no tuner in the UK will touch your ECU (remapping wise).

I've unscrambled Sard EPROMs in the past and so I can tell you what has been changed if you like. NOTE: you would have to send me copies of the EPROMs or read them in an EPROM reader and email me the scrambled binary file contents as sending the original (unique) chips in the post is not a good idea.

I've got a similar ECU for an ST205 GT4 with two Techtom boards in it and they usually have to modify the ECU lid to squeeze the extra boards in.
