Hi, I'm new to this websited, but am in need of your help. I just recently purchased my childhood dream car, 1990 Irocz Convertible. The check engine light is solid from start up on. Car runs extremely rich, and the speedo isn't working. I replaced the vss sensor, map sensor, o2 sensor and knock sensor. When I examined the ecm unit, found that it had an after market z industries high performance chip in it. The proper broadcast code for the unit is atny. I happen to be a UPS driver by trade, and have Jet Performance as one of my accounts. Spoke with them, they said I needed to hunt down the proper eprom atny. I did, and purchased one. Placed it in the ecm, still same problems. Do you think I should purchase a new ecm, and place the atny chip in it? Do I need to find the same ecm 7730 with atny sticker on it, or can I purchase a re manufactured unit from the local auto parts store? I'm confused!!

 

ron from z-industries did great tuning. ATNY gm 16145671 You have a 5.0L tpi 700r4 than ? a 1227730 is a 1227730 used in many applications remans may say 77-730 or 1227730, 16196344 and 16198262 all the same ecm.

Thanks for the quick reply. So what you're telling me, is that I can by the remanufactured 1227730 ecm, and plug my atny chip in it and it should work, hopefully? Yes, you are correct about the 5.0 engine and 700r4 trans. You see, I'm just trying to restore the car, won't need the high performance chip. Start with mechanical s, get it smogged, then do the cosmetics.

 

It depends on if the ecm is bad. Have you pulled the codes or is the ecm non responsive ?
I have a brand new axxb that would work for you and a used anjb. Its hard to know if the vats has been deleted fro the z-industries memcal ron said he does not have all the old records when he tuned for turbo city.

http://www.gearhead-efi.com/BCCFind/

 

When I placed the atny in the computer, the car starts up fine with the security light on the dash flashing then going out. My assumption the vats is still working correctly because it's still wired up beside the ecm. I also had two more keys made for the cars ignition, seems to work fine. I've removed the z-industries chip, and replaced it with the atny that I purchased off of ebay. According to the sticker on the outside of the original ecm, atny chip is needed, which I purchased and replaced. My guess is that my ecm is partially functioning, but missing some output relays or something on the board to send to the speedo and the other sensors. If you feel that a replacement 1227730 ecm with my new atny chip will work, then I'll give it a go. In other words, it sounds if the ecm is just a catalyst the eproms information to be sent and received to engine/sensors.

 

If the speedometer isn't working you could have a bad buffer in the ecm or a issue with the vss signal to the ecm. The running rich could be a bad ecm, leaking fuel pressure regulator or injectors or bad o2s.

Thanks for the info! I think I'm going to start with a new re manufactured ecm, then work on replacing the egr valve, vacuum lines, and fuel pressure regulator. Then new cap, rotor, plugs, and plug wires. Just to make sure all measures are taken to eleviate any future problems.

 

Ok, I've replaced the ecm, and put the atny chip in it. Car runs much better, and no check engine light. The only problem, is that the electric fans don't seem to come on now. My understanding is that the primary fan should come on at around 222 degrees. I've purchased a new coolant sensor, and will attempt to replace it next weekend. Hopefully that will initiate the fan/fans. The previous ecm, the primary fan would come on at ignition. I'm tempted to put the z industries chip back in to the new ecm. I think the car runs better, and the check engine light still is off. My only concern is, will it smog?

 

the fan should come on at 226F , its hard telling what modifications were made to the z-industries memcal with out doing a read on it with a eprom reader/burner and doing a compare with tuner pro or tuner cat. Ron from z-industries might be able too look at his records for you. He did live dyno tuning at turbo city and also did mail order memcals. His email is REMMIZR@aol.com and include a picture. If it was dyno tuned I think he printed that on the sticker. you issue maybe the cts acdelco 213-928 the one in the front of the intake or a relay or bad fan or wiring.

 

Just to add, if the VSS in not working, the car will not run correctly but will idle OK.
