Ya, you should have a Vacume at Idle, But soon as the S/C kicks it will start showing boost. Try it with the s/c disconnected.... its intresting

If my memory serves me correctly, we should use the Boost pressure instead of IMP. IMP would add the atmospheric pressure and not give you your boost reading. So the max 11psi you did last night without waking up your neighbors @3am sounds right. Right now with my car bone stock, the max boost pressure I get is 13.5psi.

cool. had some seat time today. seems like on the cruise the s/c is not even charging. lol...crusing at 75-80mph i'm still seeing negative. dropped it into 4th and gradually into the throttle and watched the boost climb to 15psi and still climbing and by then I'm doing 120mph and had to slow down.

switched to the IMP and then just floored it to the kick-down and the IMP went up to 33psi. LOL

also monitor the IAT today. 95F degree and my IAT cruising at 75mph is around 131F. at 90mph it went up to 141F. and then checked it again tonight on a short drive to the gym the IAT is around 95F with 70F outside temp.

well if you subtract 14.5 from 33psi...thats about 18.5 which is basically what you should be getting with a 178pulley

yea. I figure that part out after reading the other datalog thread lol

and this was on a hot day, so in theory on a cold day I should easily see 19-20psi. I didn't record it but the IMP was 33+...33.4 or .5 something like that.

certainly is more fun looking at the IMP then the actual boost gauge.

Rev. 2.0 Finally out. Pretty nice!

You can have a maximum of five gauges, you can choose where to position them. One feature I request was the ability to choose the units independently and I'm glad they did implement it Max boost was 14.7psi for a sec, then i had to let go ( from the detailed log ) ambient temp was 73F. IAT went from 95F to 140F.

One new feature was the rwhp, I will need a good stretch of road to test this out fully. On my short test run, the highest was only 275 rwhp.

Here are some screen shots:

I know this is an old thread, and this may be a stupid question, but here it is:

It says that it reads and clears "Engine Codes." Would other codes be readable and clearable by this device as well? For instance the SRS Warning I currently have?

thanks!

There is a thread started by me in the E55 forum about this as well...
