1990 b2600i Who still rebuilds ecu's?
Long time mazda owner, long time reader of this forum. First post Ive had to make that I couldnt find a current answer for. Long story short... Ordered ecu on ebay a few months ago. Worked great for less than a month. Ordered another ecu on ebay. Worked for just over a month. each time different symptoms same solution, new ecu. Now it stumbles real bad over 2k rpms. works way better with MAF unhooked. MAF tests fine w my multimeter. Im thinking ECU again but wanting to try somewhere that actually rebuilds them w/ warranty. seems AVpro is not in business anymore i guess? Who is the premier mazda ecu rebuilder. Thanks and triple thanks for all the other answers ive found.
