First couple logs with MMP inlets

MMMCOOKIES55 · 06-03-2015, 10:09 AM

Hey guys,

Got done installing the inlets last night and did a few logs after to make sure everything looks good. I am noticing some slight oscillation around 3-4k that I cannot explain, maybe a smarter eye can catch something I am not seeing in the logs, thanks!

FBO with JB4 (29), MHD JB4 backend Pump flash (93), MMP Inlets. 5992's at .022 (500 miles old).

The Car feels very strong and for the most part steady with the exception of 3-4k.

Thanks for posting the logs! Interesting to see the slight variation in boost. Maybe it has something to do the charge pipe or BOV springs or the computer adapting to the new setup?

im not sure I see the oscillation you are talking about in the logs. I do see that boost and PWM is great in the log, more left in the turbos when you want it with proper octane

also I see conservative timing. Terry suggests lowering PID gain on the JB4 if you think you are getting oscillations.

Yeah I plan on going to the E85 station friday, ill throw the MHD E85 backend in then and relog to see how well these inlets can perform

You make an awesome product btw!!
