I was told the ECU has your VIN number programmed into it. That's why some places ask for your VIN if you're going to swap out with an aftermarket one. Plus, My mechanic worked as a smog tech for a few years and advised me to find a place that would add my VIN number if I was going to do a swap...

I'm looking for a ECU for a 97 GST Spyder. I'm not sure if I can just swap out the ECU's with a different VIN in California. I'm told it would take longer to get it Smog because of it. Thanks for all the feed back guys. I think I'm going to try to send it in to get it fixed, but ECM Tuning isn't...

Hey All,I am looking at getting a new ECU because my ECU isn't reading all the sensors. It just came back from the shop and I have been running it for some time hoping it would kick back on but it hasn't. I think the ECU is shot. It's missing 5 reading, Cat back / O2 / EVAP / Cold start / and...

You know what.. I don't remember. I know I went to Auto Zone and ask them for help. I picked the one that cost the most, they had like three options, I think I paid something like 20 - 25 for it. It was one of the first things I did to the car just to be able to drive it with out the heater...

Had the same problem with my car, Switch out the thermostat and that fixed it. The car was still hot, but not after 6 hours. More like 2 1/2 it was warm. I found out that these cars do run hot, so you need to stay on top of your basic maintenance. Good luck.

I have a car wrap I'm going to do on the car. I may paint it later, but for now, the Red on the wrap will have to do. I'll post videos in a few weeks of how far I have gotten and pictures of the wrap. going to warp the spoiler soon.

Thanks man. I'm working on the intercooler upgrade now and replacing the muffler and a new cat. This is going to be the best vacation ever!

Thanks for the great info.

I just wanted to thank everyone for the help. It was the Thermostat not working. Once I got it switched out the temp gauge stayed at 50% and the fans kicked on any time it went over that and cooled it back down. The car still seems hot, compared to my other cars. Meaning the water hoses and...

One of the fans comes on and runs just fine. But the engine gets way too hot just idling, almost too hot to the touch. I would say the gauge stays at 50% for 5 to 10 minutes then goes up to 75% after 10mins of idling. These are all great ideas, I'm going to start by replacing the thermostat...

Hey everyone,I just picked up a 97 Spyder GTS and I know it's overheating but I'm not getting any kinda lights to say it is. I checked the ECU with OBD II reader and it's not giving me any error codes. The only problem I'm seeing is when I'm testing it to pass SMOG and it doesn't pass.I...
