Folks that have ATI intercooled blowers. Does ATI give you a device like a BTM to retard ignition timing, or do you run normal stock timing and just add fuel via FMU ?

Just trying to compare how ATI does it, vs Vortech, vs OEM.

No timing retard, just the FMU.

 

Thats really interesting.

OEM stuff retards timing, and vortech uses a BTM.

Retarding timing under boost spikes cylinder temperature. I'm wondering if ATI has the right approach. Since i'm intercooled, I'm thinking of ramping out timing to max around 3200rpm and leaving it there.

Those air to air intercoolers allow you to run full timing all day long. ATI has got some quality parts. Btw Im still using the FMU

 

Thats why I put an intercooler in for this year.

In regards to the FMU, I ditched that a while back. I like being able to tune fuel, rather than assuming the fuel requirements will be linear with boost.

FMU works, but tuning it yourself will allow you to get the most out of your combo. I've never done a WBO2 on one, but I'm sure they err on the safe side with the FMU.
