Map Ecu Installed

[MLDDJB]

Just installed a new map ecu in a '82 supra w/7mgte and was wondering if any body has had any "tuning" issues. Cant seem to get a KVF to register. But will read MAF readings. Wiring issue? checked 3 diff times and swear its correct.

that's not a very common piggyback system with us. The guys that have installed 7mgtes in recent years either went maft-pro or crazy standalone. a few are starting to dabble with piggybacks and standalones now. nobody that I know of has a map ecu in a mk2. check out www.supramania.com especially their 7mgte and piggyback forums. A search should return good results, and if not a new thread will definatley get some answers.

Not sure but could it be the scale is backwards on it, toyota likes to do that.
