2017 F56 Jcw with the nm power module on 91oct setting. Im only seeing a max boost of about .7 and .8 bar (which google calculates to 10.1 and 11.6psi) does that seem low or normal? also what is the normal(s) for stock boost pressures? thanks.

jcw pro exhaust
40*F
50' elevation.

 

This thread says stock pressure is 15-16 psi: https://www.northamericanmotoring.co...e-f56-jcw.html

 

ya i did find that thread but they didnt seem too sure, alot of "i think" or "seems accurate" was hoping maybe theres a definitive answer out there somewhere :/

 

Something I don't think I've seen an answer to- will you get an accurate boost number though OBD with one of the piggyback tuners? I believe they basically tell your ECU you are at mountain elevation, so it's fooled into raising the boost a bit higher. So you might be making 14 PSI, but the ECU thinks it's 10, and that's what your OBD reader says. Right?

In any case, that does sound low! I'd try it without the nm, see what happens. And check for leaks.

 

ya im going by the boost gauge in the factory cluster the non hud option. ya i might unplug
it this weekend when i have the time and see what it does.

 

i saw in my defi guage 1,1 bar max in stock f56jcw

now i running stage2 manic , its about 1,75 bar with evebturi intake , catless DP , jcw pro xhaust

 

so my boost gauge reading .7/.8 bar even with an nm module is definitely low then.

 

but i use 98 octan ....

 

Go to Amazon and order a Veep OBD reader for under $15...it will give you a true reading. My NM Module shows up to ~21psi and hits 18-19 consistently on the 100 setting

 

i have one of the bluetooth veepeak obd readers that i use to code bimmercode with, will that work? Also what app or whatever would i need to be able to read boost.

 

For a stock 2018 MINI JCW from a data logger I see manifold pressure values from 12.4 (0.85bar) psi to 14.2psi (0.97bar) with "spikes" to 18psi (1.24bar) and 19psi (1.31bar).

Various trips had different values. Average around 13.5psi (0.93bar) with spikes up to 26.4psi (1.82bar).

Or 13.3psi with an occasional spike to 24. In all cases the spikes really stand out and I do not have a good explanation for them.

Like I said this is a stock 2018 MINI JCW running 91 octane in middle mode. Not sport mode.

Oh this data was from trips back in Nov 2018 with the car almost a year old and with close to if not over 10,000 miles. While I can't tell you exactly where the car was almost certainly I was driving it to/from work and the elevation goes -- when leaving my house -- from around 500 feet above sea level to nearly 1000 feet above sea level then down to under 20 feet above sea level. Temperatures were probably in the 50F to 60F range.

I would only feel comfortable with an actual boost gauge tied into the intake manifold.... My suggestion is to get an actual boost gauge, and monitor boost without the module. Then add the module and see what happens.
