Ecu pull

[Heady]

i did a deep search in the suzuki database
A10 = E28 market, means this only for cars sold for CANADA market,
you do know all 89s , made after about April. 1989 were made in CAMI, plant in Canada for many markets not just USA and CANADA, even Germany version, and more. before April made in Itawa Japan actual, and the VIN starts with J and not 2C.
but that ECU is for canada only, and MT only.
That ECU will have a dumber EGR logic, that you will never seen problems with that.
the egr will be ok , unless it sticks open and car stalls.
other than that, there will be no EGR issues. with canada version, ours sets code 51 if EGR fails. (well unless the smog man starts waving his fat finger, LOL)

I haven’t had too many problems...I did a timing belt swap made sure it was perfectly in line with cylinder 4 TDC, set my lash, then set ignition timing last to cylinder 1. It seems for some reason it back fires a bit whenever I get over 55mph....It did misfire a whole lot and would almost jerk a bit when going 55 or over but I realized I was in too big of a hurry and got too excited and didn’t tighten the distributor bolt down tight enough lol....but whenever I fixed the ignition timing again i ran it up and down the road and it wouldn’t back fire a whole lot but you could still hear and feel it a little. Plus anything 3000 rpm and over the tac goes crazy(bounces from 3000 to 4000 and everywhere in between. Oh and I’m getting 15mpg right now. So I wanted to pull the ecu and make sure there wasn’t a problem there, I had a lot of other stuff to do to it interior wise anyways. Tank you for the awesome information if you have any pointers or advice on my problem I am all ears.
