16VT’s involvement: Wired in fuel-only Megasquirt ECU and calibrated.
Chassis: stock;
Forced induction: none.
Engine: 2 litre 8 valve 4 cylinder naturally aspirated, totally stock
Injection: Port injection, 197
cc/min Bosch injectors, original CIS injector inserts used but CIS
O-rings were installed on Bosch EFI injector.
Description: Totally stock car.
Originally CIS-E, but too much grief involved in diagnosing CIS-E
problems, hence the conversion to EFI. Ignition and idle control taken
care of by the original ECU. Air flow sensor had to be retained in
order to provide the original ECU with load signal for idle control and
ignition advance.
MSTweak was a great help in getting 14.5 AFR during most driving
conditions. AFR ~13.5 at WOT and 16 at 2000-3000rpm cruising speeds.
Running open loop without catalyst. Tuned with techedge wideband.
