Great product
Someone had converted efi to carb and hacked the electronic system up. This stand alone ignition solved my firing problem and was easy to install. Super happy with the product.

Good Product Overall
I am happy with the quality of the parts and the ease of installation. The only problem I have is that the software directions I received were not up to date. The tech support was very helpful.

Works OK, cheaper than alternatives. But, do not trust rev limiter.
I run it on my 99 TC, punched to 95ci, cams and head work. It let my engine over rev when I missed a gear and it caused the spring retainer to break in half. The results was a bent valve, chunks taken out of both heads and pistons. $900 in repairs and all is good again. I now make my own ignition curve and have all spark cut out around 6200 rpms. I do like that I can advance the rear cyl 1* and make my own curve. For the price, I'm good with it. I even put a TH ECU w/ wide band O2 sensors in my brother's 08 Electra 103 build.
