I'm using a display with real time data.
I know a pro drag tuner that uses motec ecu with all (and more) the sensors I want,
ok, no ac and idle valve there, but the rest are .

so is the data you're collecting being used to augment engine functions or not? because if it's not, then it doesn't need to go to the ECU.

you sure a motec m400 can't do idle and ac?

elior77

on drag car ac and idle are not needed.

I use the data for live view, calculations and logging for later analysis .

I can use the data in many ways, the haltech elite got this custom functions you can define.

Sounds like an application for the Extreme MS3.

Use a Haltech Elite for all critical sensors then send them out over CAN to a race capture pro or other data logger. Any other nice to have sensors can run into that. The RCP can do 8 analog and 4 digital inputs plus anything the Elite is spitting out over CAN.

Reading this thread reminds me of this for some reason.

A Life Racing F88RS could do what you need.

Depending on what you do with a dash, you can have more more inputs/outputs.

I run a F88RL with a MoTeC c125 with the I/O upgrade for extra sensors and outputs.

Price points are very reasonable for such a ecu.

RCP is very interesting, thanks !

On my LS swap car with lots of inputs/outputs, I'll be using an MS3pro and a JBPerf CAN-EGT+ expansion board. Similar capabilities to the MS3pro Ultimate.

Dwell time on wasted COP really shouldn't be an issue. Even at something like 8000rpm, you still have over 6ms of dwell time available, and that's allowing for a 1ms spark time over and above the 6ms. There's no COPs I've seen that need that much dwell, most are rated for 4ms or less.

Sequential fueling is a different matter, but unless you're running stupidly high RPM then it shouldn't be a power issue on the ignition. There are other considerations such as coil life etc of course.
