I have a 91 miata with a 1.8 swap and megasquirt now installed and I am having trouble getting the car to start. Also i went and pulled back on the throttle and tuner studio now says offline and will not reconnect.

Which Megasquirt? Any custom wiring? Has the car run on Megasquirt before the swap? Figure out if you have power getting to the ECU. If you do, take a composite log to see if you have crank/cam sensors. If that checks out, check for fuel/spark.

Its Ms pnp2
No custom wiring
It ran on the stock ecu after the swap for a year

i guarantee you that you have the spark plug wire order wrong. I had the same issue. use the 1.6 wiring order. not the 1.8

BRG_Dylan

So what is the order exactly

Oil Leak

Yep order is wrong, one second and ill show you how i have mine routed.

Oil Leak

try this and report back

Oil Leak

you will have to play around with different plug lengths, kind of annoying.

BRG_Dylan

So then would it matter if I had the 1.6 base map vs the 1.8 base map

Oil Leak

Change your engine displacement to 1800cc, and see if it wants to start.

BRG_Dylan

Ok so I should use the 1.8 map?

Oil Leak

yes, please do.

BRG_Dylan

I've been getting there errors aswell

Oil Leak

BOII.... Wut.

BRG_Dylan

also when the throttle pedal is pulled backwards it doesnt detext the ecu but then when u push it in and then let it come back on its own it detects it. But the gauge thinks the throttle is at 30%

Oil Leak

did you calibrate your TPS? Do you even have a variable TPS.

BRG_Dylan

No I dont, I'm using the stock mazda one

Oil Leak

the 1.6 doesnt have a variable tps so that reading probably is useless.

BRG_Dylan

Couldnt get it to start. I have the injector settings changed and i moved the plug wires but still nothing

BRG_Dylan

Does it matter that it's the 1.6 coil pack
