8HP CANTCU Integration

EMU PRO
1

I’ve got a running car with a GM LT1 engine and an ECUM EMU Pro 8. I’ve implemented the documented CAN interface from CANTCU, and the EMU Pro sees it just fine.

The CANTCU sees all the engine data it has requested as well (rpm, throttle position, MAP, etc. etc.).

Looking at what the CANTCU is requesting seems to boil down to a “cut %”, which I assume a ignition cut, and a “blip %”, which I assume means a throttle blip.

Given all that, can anybody provide some guidance about how I go about doing that? The CANTCU wiki has no useful information, and I don’t quite see how to do it from within ECUM Pro software.

Many thanks!

I’ve found a “Custom” ignition cut table, and I’ve put some preliminary values there. X axis is CANTCU_Cut%, with values ranging from 0 to 20 degrees corresponding to the 0 to 100% cut request coming from the trans controller. I’m not seeing anything similar for throttle blipping though…

Here you would find some guides for torque reduction, blips can be done similarly.

Thanks for that link. I’ve got a running car now with the Pro/LT1/HP70 combination. I am having some trouble with the CANTCU going into Limp Mode with code 420231 / 420331 / 420431. Is there anybody out there that might know how to investigate these codes?

Hi @parsonsj ,

last weekend I went testing the car and I added throttle blip to the strategy like this:

Cool, thanks! I’ll check it out when I get back to the shop in September
