I CAN'T Believe that this was missed....


Pulls in 3rd gear would yeild higher WHP then in 4th, and this looks as it does so here. I do not see how a UTEC would gain an absolute advantage over a Flash other then you can tune on the fly. I see how the AEM allows an advantage as you get rid of teh MAF, but if these #'s were generated in differen t gears, then they are not similar tests

 

Ya know I think I'm losing my mind, but I could have sworn there was a comment that all of the pulls were done in the same gear (3rd)?

Anyway.. The truth is that Both Dynoflash and Utec have the potential to make the same power.. My personal reason for choosing the UTEC was simply because reflashing every time I made a change would have become inconvenient. I still would get a Dynoflash in a heartbeat as a 'base tune' for my modifications. However at the moment I'm attempting to build a few maps for a stock ECU.

Its still an apples to oranges comparison, ultimately the choice between a flash and a Piggyback, or even a standalone depends on a persons needs and their desire whether or not to make frequent changes.

 

Can we stay on the topic please?

Start your own thread if you want to compare "*****" vs. "*****".

This thread is about UTEC, not Dynoflash.

There is a Dynoflash forum here for everything you need to know about Dynoflash.

Thank you

 

to talk about the knock condition. there was none. we actually turned up the knock threshold from where it was defaulted from turbo-xs. turbo-xs said when the u-tec is sent out its knock threshold is set very conservative. we actually turned the knock threshold up making it safer than stock. hope this helps eveyone with any knock questions. by the way turbo-xs has a nice tuner package that allows to actually listen for knock through headphones. it also had a beautiful wide band meter. superb product.

information for all reguarding dynoing on a dynojet all wheel drive dyno. almost 100% of the dyno that we do for an AWD 5 speed vehicle are done in 3rd gear during the tuning process. there are a few reasons for this. It is a load condition that the vehicle will probably never see on the road unless it is going up a serious hill. This is an inertia dyno and the total weight of the rollers are somwhere around 6000lbs. the vehicle weighs alot less than that so it will never see that kind of load on the street or track. with that being said, to do repeated runs in 4th gear would put an unnessesary load on the vehicle and the dyno runs would take a lot longer to do causing unneeded heat build up making it take longer for wait time in between runs becuase a minor cool down in between runs is necessary. the car would never get this hot on the road. for tuning purposes you don't need to do this. however for verifying purposes a 4th gear pull may be done at the end of the tune just to verify everything is ok. then backed up by an actual road test to check all parameters i.e. boost level, knocking, driveability, etc...

to let anyone interested know all the runs compared on this thread were done in 3rd gear. ALL COMAPRED RUNS WERE DONE IN THIRD GEAR. hope this clears up that issue. by the way I don't think we posted any race fuel plots, they will be posted soon. a comparison between pump gas and race fuel (same boost with the u-tec) will also be plotted against eachother and posted here.

 

This is essentially what i said early on in this thread. If you run the same boost, the same ignition timing and the same AFR, you will get the same results.

The car in question likely had a problem with ignition timing when Al was tuning it. If Al could have gotten the ignition timing where he wanted it, then the car would have made identical power.

This thread is not meant to compare the two products on the basis of power output. This should just be taken as a thread that shows what a UTEC can do in the hands of a shop that has years of 4g63 experience.

 

That actually was my entire point..

 

Yep, and you are 100% right.

I'd love to see the c16 plots.

 

The race gas map is the real advantage with the UTECH. Running race gas can make a huge difference. Gotta love the the fact that whenever you want to feel the affects of 30whp just pump in some race gas and switch to the race gas map and wow.

 

i guess it didn't work. It said the file was too big.

 

Any ideas how much you guys were able to increase ignition advance on c16?

Usually on a wrx we ca add another 4 to 5 degrees on the top end.

 

We did not add that much. We are not trying to push the limit with customers cars, however you might be able to get away with that much or more. We save all the experimenting for our own car and based on what we know from our 548 wheel horsepower EVO 8 we can get away with alot more, but you definitly need a bigger turbo to do so.

 

<----- must get parts on asap and run to the dyno to get tuned.

 

Nice gains!!!

 

How much boost is the car running on the pump gas map?!? Why will nobody answer this question?
