Changed from MAF to IAT on MS1
Hi,
today I installed the GM IAT on my '92 Miata Turbo. The car has an MS1 PNP and without the drop down like the MS2 has I am to stupid to get the car running again.
I read about "easy therm" and i also found the right data for the bias. Coolant Sensor is stock 1.6 Miata.
But I can't write it to the MS. Only an Error shows up.
Someone in this Forum said that he had to change the settings of his PC into US/English like Time and language. But also that didn't work :(
I bought this car with MS1 and oem AFM. Next to this car i had built an Miata 1,6 Turbo with MS2 which was damn easy to calibrate that GM IAT Sensor.
Can someone please help me?

AAAAAAH
Do I need to jump the fuel Pump on the MAF plug?
There are 3 different ways shown:
1. Megasquirt instruction - connecting the IAT kabels to 1 and 6 on the MAF plug
2. Plug IAT in 1 and 3 and jump 2 and 7 for the fuel Pump https://www.miataturbo.net/megasquir...problem-92105/
3. Plug IAT in 2 and 3 and jump 1 and 7 (jump 2p andFP). Also from this forum but i can't find the thread again
What is the right way????

Okay i solved some issues today.
1. if you choose the ms1 base map with Maf then your car won't Even Start with an IAT
2. So i took the "with IAT" base map and wrote my working tune into it. Fuel, Spark, Engine constants...
3. i had no connection to MS because my data cable had a fault. So i built a new one.
long story short: my car is running! With IAT!
but it runs super lean and stalls after short Time.
i dont know why. The tune is the same as betore except the maf which is now an IAT.....
do really to make a new tune now?
