Log Review: FOB, Pure S2 hi-flows
 
4 Attachment(s)
Hi All,
Just recently installed pure stage 2 hi-flows with relocated vrsf inlets 2".
Looking to get the boost turned up as I just finished breaking-in my spec 3+ clutch/steel smfw. On 93 oct fuel atm.

FOB with stage 2 lpfp
Using PUMP JB4 BEF
Map 2 for now
Fuel: 93 oct pump (100 race & E85 available)

I took a few baseline logs after reading the upgraded hybrid posts. I am overboosting a bit so I figured I would ask here for advice before turning it up.

I've got more logs if needed but I will attach three 3rd gear runs and a bonus 2-4 gear run I got the other night.

Side note: Ambient temps were ~72F, and as I suspected I am seeing an uptick in IATs with the relocated inlets even with the 335d intake scoop.

Thanks for your time!

Mike

Bump because I will be in a similar situation soon and would like to see expert guidance on your logs.

To my novice eyes it looks pretty good aside from noisy cylinder 5, over-boosting at the start of a pull, and pulled timing probably due to octane deficiency.

In general this looks solid.

A few timing corrections, but likely that’s just from utilizing 93

I think it’s safe to start introducing some e85- it’ll be a balancing act between fueling

We can start with e20-30 If you want

Back with 4 runs on ~E30. Same settings and I also reset adaptations.

Ambient temps were around 65F tonight.

Looks like on the first run I had some real overboost issues, but they seemed to get better as it learned. By run 4 I was still overboosting but I didn't feel throttle closures like I felt on the first 2 runs.

Thoughts? Thanks guys!

Overall looks pretty clean- the last log being best.

Definitely some room to bump up

Thanks Dave. Should I remain on Map 2? Also, in regards to over shooting target would I need any changes to my settings?

You can bump up to the next map.

We can see what fueling & timing looks like.

The overboosting early on in the pull, we can monitor , but that might adapt down a bit- if not we can fix with duty bias
