In 2017, I sent my stock 2008 ECU down to Smart Madness to be flashed with their ECU Tuning. I also bought the air intake kit. I already owned the GoPedal. I installed the unit and the power difference was wonderful. When it came time to get my ride smog tested, I removed the air intake kit and returned the stock air box. But I cannot pass CA Smog.

The problem I now have is the Smart Madness http://www.smartcarofamerica.com/forums/editpost.php?do=editpost&p=1626345ECU Tuning is not detectable by three different CA smog test units, one of which is at San Francisco Smart Center. After two local smog test shops said, "our test computer cannot detect your car", I took my ride into the SF Smart dealer and they found pins 4 and 5 on my OBII module were bent. So, they replaced the pins and re=tested with their own smog unit. However, the SF Smart dealership smog test system could not detect my ECM!

Question: Has anyone had any problems with the Smart Madness ECU Tuning?

I have contacted Smart Madness for help. They are investigating.

Keep us posted relative to Smart madness's response.
Thanks

You may need to swap to an ECU unit that was never flashed. That way you can at least pass your certifications while you try to figure things out. A used ECU unit shouldn't be too hard to find.

A used ECU will not have the correct VIN

The San Francisco Smart dealership put in a brand new ECU and all diagnostics passed. This proves the problem is with my ECU. Recall, the car drives great with my ECU flashed by Smart Madness, but CA Smog computers and the dealership diagnostics computer cannot see the ECU. There is no way of knowing of the problem was associated with the Smart Madness ECU tune or not.

Smart Madness has been generous with their time by taking my calls and sharing ideas how to proceed. With my old ECU and performance tune working well (except for computer detection), I can simply swap ECU and drive the car for 50 miles to yield 'ready' state for all the internal monitors. Go pass smog and put back in my performance ECU. Yes, this is a bot of a pain, but not too bad and worth the performance my Smart Madness tuned ECU provides.

Happy to hear.

I’ve been wanting to turbo my smart, but that would put me in the same position as you. Swap a bunch of stuff every 2 years for a week. Made it seem not worth it to me. A ecu swap, sure. Few minutes and done.

Just curious, what was the cost of the new ECU?
