and I hate posts that sound like they are trying to start some type of drama.

~12-13 lbs stock to 16.5 lbs tuned isn't "only a .5 psi" increase.

 

I'm just asking because people talk bad about the unichip as if they knew about tuning and wanted to see their knowledge about the RMW since its suppose to be much more reliable and grant much more power.

 

The unichip was definitely running more boost than Jan's tune. The big difference is Jan wants to stay in a safe zone. The other difference is Jan can tweak the timing and AF to each individual car where the unichip was a canned tune. With tweaking you can get the max SAFE power.

The unichip gave my 07 S awesome power but it also gave me tons of CELs (until I finally got a good harness) and occasional engine "super knock" from having either boost too high or timing too advanced for the 92 octane gas we have here. I didn't make up the term "super knock" either. It was printed on the diagnostic sheets the MINI techs would print out each time I came in for service. "Super Knock" does not cause a CEL but it will store a fault in the ECU.

My JCW with the DIMSPORT mild blind tune (meaning the tuner didn't want to push anything very far since we weren't on a dyno and I haven't installed a boost gauge) has more butt dyno power than my 07 with the unichip. At the same time I feel confident it is "safe".

for giggles my 07 S dynoed 203hp and 237 lbs torque atw with the unichip.

 

Sure Richi's post was directed at me....but your answer is thorough and accurate.

MotorMouth is correct.....16.5psi is the target boost level mine is set at. Generally this only occurs during overboost, where I'll see 16-17psi depending on a variety of factors. Most of the time in non-beat on the car mode...I'm seeing about 15ish psi.

And I'm going to go on a limb and say that the UniChip might infact give better peak numbers...so if thats what you're excited about thats the ticket. However, a dyno tune is going to yield a much broader torque curve and gains across the board...all while being suited to your car to ensure that maximum safety limits are observed.

 

am i missing something here? wher are you getting your stock boost numbers from ? with all my mods ( check signature ) my boost numbers are varying 10-12psi, with overboost its about 14psi... whats wrong with this picture?

 

^^ +1 - I have similar mods, just installed my boost gauge this weekend, and peaked out at 13 but usually 10-12. 16.5 sounds good to me. Also, sorry for the newbie question, but what and when does overboost do and occur?? Thanks in advance

 

I am asking because it seems awkward for a tune to make more horsepower on lower boost levels/not as an advanced timing. Of course a/f is a main factor but can be adjusted by both tunes. For the last 2 posts, I dunno, without the unichip I was peaking at 15 and sometimes almost 16. Did you get an update on your software?

 

Good information from a known source.

MM, what type of dyno was used for the 07 S? Was the a/f probe at the tail pipe?

Thank you,
Don

 

It was on a Dynojet and AF was measured with a tailpipe sniffer which is known not to be very accurate due to the catalytic converters.

I have sourced a new dyno that takes the reading from the O2 sensor. When I get the time to dyno tune the JCW (and time to install my boost gauge before teh dyno tune) I'll use this one.

A friends 07 S was dyno tuned on it (using dimsport) and his A/F stayed below 13:1 in the full rpm range but he didn't have a boost gauge so the tuner didn't push the boost too far. He ended up with 217lbs torque ATW. The friend has installed a boost gauge since then and it shows him peaking ~15 lbs boost.

 

MM,

Do you think the new dyno your using is reading a little lower than the DynoJet? 217TQ at the wheels is nice.

Don

 

The new dyno is also a dynojet - it just uses a different type of sensor for measuring AF.

Since the two 07 cars were dynoed on different days and with different dynos (even if same brand) I wouldn't expect the readings to be calibrated to each other.

 

Rumors would be something that have happened a few posts ago.

 

if those are stock boost speeds...then maybe theres something wrong with mine
overboost im at 16-17psi tapering to about 10
regularly boosting at 14-15 average
08 mcs

 

I'm showing how high stock boost levels can be. What mods do you have?

 

signature updated

 

your gonna need a bigger mixer than that to stir the pot.

 

does he know what's mixing in your pot?

 

hahahaha figured I'd just keep it simple this time around

indeed!

 

I want your pot...

 

ThumperMCS - Dyno results!!??

The people demand data!

 

Stir all you want, nice to see you have a revision.

A dyno sheet with A/F would be the proof most of us are waiting/wanting to see.

Not one of those wimpy, you can barely read dyno pictures, either.

Jan, how goes the reflash tool and the R56 power curves? I'm up to about 8 in Denver that are interested, 5 or 6 R56 variants.

Don

 

this was just driveability........ since Thumpers car had a DDM intake the maf was interpreting some things differently....... smooth as butter now

working on flash tool for the R56.......... I'll call and see where we care on it
My son is graduating this weekend so no dynoing till next week

 

Ill be your best friend, if you post some dyno sheets.

 

Oh dear this could get out of hand...

 

congrats to your son! excited for next week dyno results!
