STATUS: Pending ethanol and camshafts stage 2 upgrade
This is my first encounter with standalone EMS. Previous setup was MAFT GEN2 together with stock ECU which gave a little control over the air flow, and was pretty good in logging AFR and other useful stuff.
7M-GTE modifications:
- Engine arrangement, Number of cylinders: ...
- 1 or 2 (or 4) cams to be controlled ?
- signal pattern ?
- Eagle rods
- HKS 2mm ML head gasket
- ARP head studs
- Garrett GT4088R
- 2.5" intake, intercooler (21"11"3")
- 3" exhaust
- 1000cc RC injectors
Was ECU originally ordered for another project ? Or purchased secondhand?
