i have evotech software pulley intake exhaust webb tb and milteck header
I WISH I WAS RICH BUT NOT MY CAR IT SUCKS
anyone have any ideas of what to do i am in contact with evotech but i dont know yet if they will do anything to richen the mix any other ideas solutions?

 

Two places to contact:
Evotech and Randy Webb- He is on a trip to Atlanta but should be back on tuesday- just leave a message.

 

I assume the relatively low hp readings, given your mods (170hp or so) and the way rich A/F ,11,0) is what is bugging you

you have discovered the need for a real tuner as opposed to a bolt-on artist posing as a tuner.

A few minis, mine included, seem to be under achievers, producing 15-20 hp lower than equally modded cars. In my case, I am convinced flow restriction in the head is the bottle neck.

 

I noticed on your site that your car has a "Custom Intake System". With the Rich mixture you either have an airflow restriction (intake or exhaust) or you have a fuel delivery problem. It's would be hard to believe that the computer controlled side (fuel) would be delivering too much fuel so I would check the intake system for airflow restrictions or possibly a defective exhaust header? Would be great if you could swap parts out with another car to determin the problem.

 

ya i have a new intake on the way so i will test that to see if it helps i hope so but what really bothers me is how rich it is the graph will only read to 10 but it seems like it gets much richer than that in the higher rpms which is real bad preformance wise.

 

anyone know what kind of sencor the mini uses to regulate the airflow? and where it is located.

 

at WOT, which is where you are when making a dyno pass, the ECU isn't looking at the O2 sensor. The extra richness is a gift from the fuel map, fuel pressure, actual amount of air getting in, and your injector flowrate.

 

this is really frustrating. i have spent a lot of $ on this car and it is fast but my hp going down after adding headers and a tb is lame. my tq is up 10 but the hp is not anywhere near where it should be. :???:

 

Randy will be down in town in four days. Maybe he can help you with your car. I'll even give my pulley time spot on Saturday AM so he can take a look at your car. Don't worry, I can always get the pulley done in Vegas in Feb. :smile:

 

given your mods, what do you think it should be?

 

at least 185

 

jlm said it; some MINI's are duds from the factory. It seems my 2nd MCS is significantly more powerful out of the box than my 1st one was. Do you happen to have a baseline dyno (w/out any mods)? Sorry to hear that your MINI isn't dynoing to what you hoped, but I'd say that the main point is: are you pleased with its' performance on the asphalt?

Also, peak HP dropping is not reason for concern, espeically if your torque improves! What you're really looking for is area under the curve.

ya the real driving feel is much better with all the mods very happy with that i would just like to get it tuned just right which proves to be a challenge on a car that is basicly run on computers. and they are still pretty new.

 

I hope mine isnt a dud.. That is my luck though. Im going to have to drive a new bud in towns MINI S and see what it feels like...

 

"you have discovered the need for a real tuner as opposed to a bolt on artist"

I received a complaint about my above remark, which was apparently seen as a personal attack. Following is my response.

My statement was intended to address the possible consequence of bolting on parts with claimed but un-realized value. What is needed is tuning, such as flow testing the head, modifying the combustion chamber shape, altering port shape and flow velocities, measuring and revising the A/F ratios, etc. If you think there are tuners of this sort out there, please inform us all. Instead, what is rampant, are hp claims for this or that header, exhaust, intake, chip, pulley %, etc....but few of these claims were arrived at through tuning by anyone selling them or representing them on this forum.
I have great respect for the real tuner and stand by my remark.

 

tuning is a part of getting any car to be faster in the most effective way possible i fully agree and seeing that no "tuner" has contacted me it seems to be evident that they are either not present on this site or they dont care. the place that dynoed my car tunes wrx's and they are doing their best to help me out but since they dont yet do software tuning for the mini the chances of them being able to help me is up to the germans at evotech. if anyone has the resorces to help me it would be great. i dont see why anyone should bash jlm because he is one of the few who have given me any imput. i would love to here from anyone who has any ideas. espesially if they can work with my ecu i have no problem paying $ to get my car to where i want it to be and i am not sure if evo will do anything. thanks

DynoDynamics tend to give lower whp than, say, a Dynojet. These guys use the same type of dyno and you can see some results:

http://www.ktrperformance.com/servic...graph_main.htm

Looks like you are seeing a peak of about 170 whp, but you don't have a stock baseline graph. Without any other information, I don't see that as necessarily being a bad result.

As far as your A/F plot, that definitely looks rich, but so do most MCS engines, stock or modded. It looks like SOME Evotech and SOME Powerchip files lean out the mixture, while some files do not. Also, was this a tailpipe sniffer, or do you have a bung welded upstream of the cat? That can make a measurable but unpredictable difference.

jlm is spot-on about the "tuners". Frankly, it's way easier and more profitable to bolt on parts and come up with dubious hp gains, than it is to thoroughly test parts, make tweaks for specific vehicles, then test again. There is nothing at all wrong with selling parts and installing parts, but it is misleading to call yourself a "tuner" if you can't and don't tune anything.

Software to actually tune the MCS' ECU (or DME if you prefer) is certainly available, but it starts at around $10,000. So, to justify that expense, you'd need to plan on doing custom chips for lots of vehicles. And, even then, there is no guarantee of results. It's way easier to make your engine run WORSE than it is to make it run better.

I'd suggest being persistent with Evotech, after all, they presumably have the tools to tweak the maps (unless they are contracting that work out, as is common in the industry). You have already invested in their product, so get the most out of their technical support. Send them your plots if you haven't already, and let us know what happens.

jlm,

I agree with you that just because someone says, "It will give you 20 more HP" doesn't mean it will. I jush wish my friend worked on MINIs instead of Chevys.

I could be wrong on this but from what I know, Evotech is contracted out and most. although not all, of the ECU upgrades out there were writtten by the same guy in Germany.

 

Then they'll have to call Herr H.

 

I just went to your site Minicoop78 and your exhast the dual one that looks like the rogue.

Thats your problem, if its anything like the rogue your in trouble because I had it too.

Anyone else have that POS? I gained 10hp at the wheels when I tossed that.

 

I had the Rogue when my car was underperforming and suspected it as well. However, after an exhaustive day on the dyno, found that the Rogue on my car actually gave 5 or 6 hp more than: stock, supertrapp,. We did the Rogue, then stock, then supertrapp then Rogue all on the same day. I also found better track times using the rogue compard to the supertrapp.

 

thanks problem solved my old intake i think was suckin. custom job got the alta and much better look at the never seen a dyno thread. charts and video much much happier. still not sure what the heck was going on but its all good now.

 

That Borla Sport exhaust sounds really nice on your car. Not as loud as the custom job you had on there, but the borla Sport has a nice deep throaty sound. The new alta intake system looks super nice under your bonnet.
The power increase must be a nice feeling. You're car has 10+ more HP over that JCW car that they dyno'd just before yours. Thanks for letting me take your car for a spin. That's the fastest car I've ever driven in my life (yes, I know, I've lead a pretty sheltered life...automobile wise).

 

Glad to hear it was sorted out!!!

I have also gotten over my initial "Dynophobia" by racing another equally equiped MCS. I pulled him in every situation, which is good enough for me as far as soothing my "I got a dud MINI" feelings.

See another happy ending!
