[Mongoose]

Boost readings were from top of my head(and wrong lol)

Heres the Mappers email to me about a few things.

I wouldn’t say it’s “complete”, like i say, there’s plenty more testing yet.

Lambda is close to standard, they run quite rich higher up in the rev range anyway. Lambda starts at 14:1 and ends up at around 11:1 at the limiter.

Lambda is based on EGT, they run the lambda as lean as possible for efficiency and wait for the EGT to raise before increasing the fuelling.

Initial boost is un-changed, if anything with the ignition angle modifications it’s a little lower. Higher up in the rev range where we’re making higher horsepower standard boost was 13.9psi and is now up to 18.6psi.

Boost initially is 17.6 as standard and then creeps up to 18psi towards the top end of the rev range to aid with the standard torque level and modified power level. Boost obviously varies on engine load, the ecu doesn’t run on a boost request as such, it actually bases it’s request on a target cylinder filling level. Effectively volumetric efficiency.

Maps edited include cylinder filling, torque limiter, expected air mass flow, lambda target, ignition angle etc
