Re: Yani's TT6 Miata - HellenNB1

Nice, I assume you have a Dynojet? I'll be needing one in about a month. I'll be looking to get probably 2-3 different power tunes. The shop I used to work for had a dynojet. I bought it when they closed up, and then sold it after a few years. The shop I tune out of currently has a Mustang MD1750. ...

Boost control tuning

Jimmy asked me about how to go about tuning boost control for his twincharged merc. This is the general procedure I would follow: 1. Figure out the LEAST amount of boost you want the turbocharger to run. Put this wastegate spring in the WG. 2. Unplug electrically any boost control solenoids. You wan...

Re: On v12 banks

The Huracan and R8 both STILL use dual ECUs for the V10 configuration, and that's a LOT more recent than 2010. (ME17) The best option here is to run the V12 as two independent I6 that share a common set of rotation speed sensors (cam, crank) IMHO. You can bandaid things some with individual cylinder...

Why not just use coils with builtin ignitor modules, and use 8 of them? They're cheap, plentiful, reliable, strong.

Re: Cranking / starting part 1

Matthew Kennedy suggests:

"60mg fuel / liter of displacement for each cylinder is a much better estimation for cranking fuel."

i.e. 5.3L V8 = 5.3L/8 = 0.666L / cylinder * 60mg/L = 37mg cranking


As of today (12-14-2021) priming logic is too new to have well defined suggestions.
