Lightning fast shipment. Even call my cell phone to make sure I would be home when the item arrived. Part was installed in 20 minutes, My 1986 gn is back on the road. Thank You…
Replaced ecm withhighway stars ecm, works as suspected and fast shipping, thanks!!
I needed a replacement ecm for my 1986 GN mainly because the original ecm would not remember the tune on my turbo tweak chip. When I would gently tap on the side of the ecm—the engine would go into limp Home mode and barely run. SES light would flash quickly and car would stall. After 30 plus years—I am sure a driver or board internally in the ecm was failing. New ecm and car runs great. Thanks again.
Plugged in and ECM working like new!
Product was competively priced & arrived promptly. So far the ecm works just as advertised. No complaints at all
