Hi guys. I went for another drive now that I have the MS1v3 dialed in a bit better.

The car is nicely driveable now, but when I go into boost (up to about 4psi) it feels 'flat'. It doesn't seem to pull as I would expect. I went into boost a few times, but since it didn't feel right I backed off. I went back thru the datalog and nothing seems out of the ordinary to me - AFR's sit in the high 11's and timing sits around 13deg. Am I missing something? I didn't want to rev it any higher.

My datalog is 111kB (zipped), so I cant upload it, is there a way to trim it down so I can upload it? or if someone can provide an email that i can send to for analysis?

Thanks in advance for any advice!

S4 13bT standard ports
FMIC
Exhaust etc
Basically stock

 

you should be running more than 13 deg. at 4 psi

 

have just been searching around the net and coming to the conclusion that this is likely my problem, as you suggest. Seems people are running around 20-25deg at 0-10psi.

I'm using Aaron Cake's advance table which is pretty much 13deg everywhere in boost. I realise this is deliberately a very very safe map, just didn't think it would be too far off. What would you consider to be a better advance to try? Was thinking of bumping it up to 20deg and trying that. The engine is stock and I only want to run around 5-7psi. Thanks

 

i use like 22deg and 8 split

 

I'm running leading only, so should be able to run a bit more like 25deg without any problems I'm thinking. Apparently detonation is more commonly caused by over-advanced timing around the trailing plugs? Only want to run low boost (5-7 psi or so)
