Innovate LM2 and EFI
« on: October 16, 2018, 03:06:51 PM »
When I first starting looking at injection for the Mini, all I wanted to do was replicate what Rover had in the MPi, but have the ability to compensate for mild tuning upgrades.
I settled on a MegaSquirt variant as it appeared people in the UK were having some success. One of the issues with the A-Series is the inlet manifold configuration and maintaining balanced fuel delivery to all four cylinders through two inlet ports.

Innovate had their LM2 which allows the monitoring of two ports. It seemed like a good idea. I borrowed a friend's LM1 and it seemed to work well.

I did not have an exhaust at that point with two sensor bungs, so I tested with the tailpipe clamp. I pulled it out yesterday to jog my memory about its use.

The tailpipe measurement is off due to airflow at the exhaust tip. I am not sure this can be rectified. At higher RPMs, it is more accurate.

I've heard at the tailpipe reads half a point leaner at cruise and almost the same under full load.  If I did the tailpipe wideband I would compare it side by side to my wideband mounted off the Y pipe, to "calibrate".

The other issue I had once I got the injection going and the dual sensors is that the induction setup for monitoring engine speed was very unreliable. I was trying to coordinate the two systems(SC and Innovate) and use RPMs to do that.

In the long run it was easier to adapt/convert the stock MPi narrowband to a wideband. I think the new SC DELTA ECU allow for the monitoring of two lambda sensors which could be useful. SC sell the Spartan brand of lambda controller and it comes with the Rover style cable plug. All the data is in one log/location that way.

I am now using the stock style MPi/SPi exhaust manifold which may not be the best location for a wide band, but it does monitor both inner and outer banks of cylinders.

Their support left something to be desired as well, but eventually I got them to take the unit back and fully check it. Whether they really did anything or not I don't know. I upgraded to the 4.9 sensors as well, so if any one needs 4.2 sensors or Innovate 4.2 cables, let me know.

And the extension cable will not be any use as it is for the Innovate plug, so it is really just a longer cable and not an extension
