Hi all,
Second time writing this so hopefully posts this time, I'll keep it short this time.
I've got a Mk1 MX5 1.8 93' plate, that I'm in the process of trying to fit a DIY-EFI CORE4 Speeduino to. Trying to get the car setup to run naturally aspirated before switching to a GT2554R turbo kit, I've got sat waiting to go on.
I've fitted up everything, following the available information I have (for essentially a plug and play kit), but currently can't get the car to start, it's just cranking and nothing else. I'm hooking the car up to a second car during start up attempts to make sure it's got enough juice, as it's been sat a month or two.
Cars got the following:
1.8 VTPS
GM IAT
Stock Coolant Sensor (RX-7_CLT(S4 & S5))
1.8 base map pre-loaded by DIY-EFI prior to shipping
TDC set (+7 Trigger Angle)
Set Required fuel settings (mk1 1.8, with mk2 2.8 injectors (255cc))
I've got all relevant signals working in Tunerstudio when I connect up my laptop.
Currently not sure where I'm going wrong here, I've got spark, fuel and cranking. I can't download the 1.8 basemap on my work laptop (only one I have access to) to try compare and see if I've managed to mess something up.
Would really appreciate some help, I've got the tuner lined up to road tune the car, but I wanted to get it started first (at least).
Tune should be attached.
Cheers,
Scott
