Ok now I'm all good.

Resetting the pro has fixed the bin issue.

After lots of reading I found out that a logger cable can ground out the speedsensor on the diagnostic port. I unplugged the logger a voala, I got a speedometer again.

So all in all looks like my wiring is 100% .

After finally installing a friends unit temporarily to try to solve an ignition issue, I found that my car both ran smoother and didn't stall out no matter how much I would move the unit.

The maftpro was not my ignition issue, but I am concerned how someone elses unit with my bin uploaded cause my car to run better. I would also like to know what I should do to fix the loose connection issue.
I have the same issue. Just putting a little pressure on the connectors causes the car to stumble. I've tied up the cables so they don't move (much), but I still get inconsistent AFR readouts. I was considering soldering the wires to the PCB. What do you think?

Have tried unplugging and plugging it in a few times? Also take a look at the connector, the pins might be too stretched out - if so take a needle and bend them inward.

It has nothing to do with the connectors and/or wires. i have done everything I could think of to fix the issue, including replacing the wires/connectors.. with the exception of replacing the maftpro or opening it up to modify it.

Like I said, plugged someone elses up and no issue whatsoever.

I was responding to Spyder95. But with your car I'm at a loss - perhaps you need to send your unit to Bob. Sounds like a hardware issue.

DSM sidemounts would be a good option for you

EDIT: I bet if you looked at you air temp you will see the rise in temp
good suggestion on the dsm sidemounts, i'm lookin into a set right now...

Hi,

How do you make this Maft Pro thing pull fuel when you back out of the throttle?

I've got throttle body size set to 7 (tried 6).
TPS Enrich is 0.72 (tried various upto 0.8)
Decay is 0.5 (tried various)

When a lift, it goes rich as 10.3 to 1.

Cheers,
Paul.

Hi,

I can do that. The attached bin is the latest iteration.
I've got closer to ideal before, then decided to move the goal
posts. This thing really goes now. Only 12psi at mo. Doing a cambelt
change before trying it at 18psi.

Paul.

You need to set up the MAF Limiting stuff (and a starting point):

MAF Limit TPS Threshold (.06v above your idle tps value)
MAF Limit (6.00)
MAF Limit / KRPM (2.00)
MAF Limit RPM Min (1600)
MAF Limit Time (1.50)
