I have a M7 throttle body which a few weeks ago would not calibrate at car start anymore (according to the fault given by the ECU). Result was a MCS running in limp-mode because the car does not know which gaspedal position corresponds with which throttle body position. The throttle body reacted however, so I assume there is nothing wrong with the M7 throttle body mechanically.

After many many car starts the M7 throttle body calibrated and I got home. After exchanging the throttle body back to stock the car ran without problems immediately and has done so eversince.

Can I exchange the electronics between the stock and M7 throttle body to get the M7 throttle body working again? I would like to know on forehand if this is possible, before opening up both throttle bodies.

 

Funny, that sounds like the same problem i was having with my DINAN tb... the cars at the dealer now getting a updated DINAN Tb.

 

I think it's pretty well documented on these forums that throttle bodies are a complete waste of money and cause more problems than anything.

Believe what you want though .

 

Exchange it for a USS.

 

Ok, that is one mod I will not be doing...

 

27 bucks in machining costs, and your old throttle body to machine and sell for $399. What a bargain!

 

It happens to be that I have modified throttle body where the plastic cog wheels are replaced by metal ones. It is a throttle body prepped for race use, in these conditions the plastic cog wheels wear down to fast. So I would like to use this throttle body regardless of power gains or not (which are a little there because I run the compressor on max rpm).

 

It seems at times that there is an unreasonable hatred for all things M7 regardless of the research or development behind their products.

Certain NAMers just cannot stomach anyone's business interest in making a profit on what they sell as well, whether it be M7, ALTA, or Revolution Mini.

Nick - if you represent MINICORSA then I'm getting to think you have bigger issues then just competition in the marketplace. Short quips prove nothing regardless of your number of mods.

I don't represent any company, I'm just a consumer and I'm getting pretty tired of the constant short-sightedness of some of the vendors and their groupies here on NAM.

Why should I purchase anything from a company that's constantly in a pissing contest with anyone else? I like Jan's stuff and I'd like to spend a sizeable amount of money for what he has in the near future but I beginning to think MINICORSA is not a company that can be trusted to give unbiased advice in such large transactions.

 

Firstly, I don't represent any company, I represent myself, I have no vested interest in either RMW or MINICORSA other than the fact that Danny and Jan are friends. Considering between the two of them i've spent close to $8,000 (Hell probably closer to $10k by now), and I love the work both of them do, I promote them in my signature, I don't recall there being any site rules that require advertising fee's for me to paste a friend's website in my signature .

Secondly, he doesn't even make any performance parts! He operates a repair shop, and occasionally installs parts from Alta, Craven, Ireland, etc. Jan (RMW) uses him as an install shop because he does good work at fair prices, and has a reputation for not taking forever (Not to mention he actually knows what he's doing, which helps).

For the record, I work in IT for a Non-Profit Organization, and i'm a Freelance Photographer. I usually end up working 50-60 hours a week. Trust me, I don't have time to work for either Danny or Jan right now.

Frankly I think it's a bit naive of you to just jump into a thread and start issuing accusations about my ability to post relevant "Unbiased" information in a thread. I have close to $30,000 invested in my car (That's ON TOP of the $32,600 purchase price), most of which could have been saved if I actually had someone to guide me along the way to parts that actually worked, not to mention they could have saved me a lot of headaches.

Having created two MINI's with almost 275 BHP each (My current MINI is my second MINI), with the help of some of the best tuners out there, some of whom having cars making a LOT more HP than anyone on these boards is ever going to make, I think I'm capable of sharing an unbiased, qualified opinion on an oversized throttle body .

M7?:
It just so happens i've spent well over $1,500 at M7. My post has nothing to do with M7 anything, quite a few companies make a larger throttle body, none of them do a damn thing (The stock TB has been tested to applications well above 300 wHP with no issues at all). Don't believe me? Ask some of the people making 250-300 HP to the wheels. I guarantee you they're not doing it with a throttle body, regardless of who makes it.

To the OP:
I have no idea why you think the stock TB isn't up to the task on a race track. Plenty of MINI owners have significant track time on stock TB's with absolutely no issues. Off the top of my head I could name at least 15 people who collectively have probably run 50,000 miles on the track in the last 3 years. I don't recall anyone ever mentioning a plastic gear in their throttle body failing due to "Abuse".

 

275? Give me a break... ...your sig says 230...
and the last time it was discussed on here your dyno was like 206 or something.

Your car is making more power than Jan's 255hp() GP? Maybe we should all just make up some ridiculous HP number and post on here...please.

 

Mine is tuned by NASA and it has like...1000 horsepower!

No but, usually a bigger throttle body provides more immediate throttle response and improved drivability for the mini. Not much for horsepower, just wakes it up a little, compliments your other mods and makes the car a bit more useable.

 

I said HP, not wHP, not to mention I said almost. 260-275 depending on what drivetrain losses are, weather conditions, etc. Since I have no idea what actual drivetrain losses are, I guessed, surely someone as well versed as yourself in performance modding must know the difference between wHP and BHP.

Jan's car makes 255 wHP, that's 285-290 BHP, so no, I don't make as much power as his car (the power isn't the impressive part, the fact that it's basically a stock JCW setup aside from the stroker kit and making that HP with 210 ft/lbs of torque is).

We also haven't adjusted the factory timing maps on my car, all we did was change the fuel trims, not to mention the stated HP figures are at ~7200 when my actual redline is 8150.

Regardless of whether my car makes 260 HP or 275, you'd have to be an idiot after all the testing people have done to actually think that a TB does something.

 

Get a flywheel if you want throttle response, it doesn't throw codes and doesn't send the car into limp mode every 10k miles.

 

I know what you said, I quoted what you said. I do know the difference between WHP and BHP, but seeing as you didn't originally specify which you were referring to, I can only guess as to what you're saying.



I made no mention in my post pertaining to TBs, whether they work or not, I don't really care...
but, I would have to be an idiot to believe that your car makes any where near 275 BHP or WHP.
Next week you'll be claiming 300 horsey power...

 

Is it getting hot in here, or is it just me?

 

yes just hot air from the hp challenged

 

The whole TB thing got started when Randy Webb posted that his TB was dyno tested to make something like 5whp.... in those days 5whp was alot..... then the TBs started to "happen"..... I have an M7 which does not throw codes....(I have other things that do that) but I can't make any claims about the dif good or bad..... there are a lot of mods that have been proven to not do $h!t..... the TB mod is not one I can endorse since there are plenty of cars making power without it and throttle response from one car in particular wo a TB is startling....... one would think that the extra capacity could be used to make power

 

Whatever you say . I have the dyno plots and know what's done (And what we have left to do). This isn't secret information. My dyno is published in the 231 whp thread.

 

So, what size TB did you purchase, and why? Are you also saying that in all the mods and engine/supercharger/etc. changes you've made that the TB never made a difference?

 

I did the TB mod, was tossing codes and it made no difference in the way the car drove. Pulled it after 1k miles or so. Sold at a loss and I had to purchase a new OEM unit since there is a core charge when originally purchased.

 

Let's ease up a bit on name calling and rhetoric a bit, shall we? This thread can stand well enough on it's own without the potential ill will.

Many people might not gain a whole lot of upper end hp with an enlarged TB depending on their mods, but because a larger TB begins to flow more air at a given throttle angle than a smaller one, this does tend to make the engine feel a tad more 'responsive'. It's the same thing as putting a short throttle bellcrank on a cable operated TB or a carb. It's also this increased airflow at smaller angles that confuse some EFI systems when it tries to determine throttle opening.

 

I didn't post this question to fire up the whole TB discussion again (and more)
Meanwhile I still don't know if the elektronics can be swapped easily, and M7 is also not responding to my question(s). Which is a pitty because their broken down TB body caused me a lot of inconvenience, I had to end a motoring weekend and visit to the Ring because of it.

I'm only putting the TB back if can also get a wider tube from TB to compressor, see what that does (see picture).

 

When you called the office did you talk to Peter about this issue ? We have not had much time for the boards lately.

I just got a response over e-mail from Shelly with apologies for the late reply so thats nice. I gave some additional information so I hope we can get the throttle body repaired, so far it's looking good. I also asked in my e-mails for two washers and nut inserts which were missing in my (second hand but never used) M7 understrut system. That's looking good too. Thank you.

 

All issues have been cleared with M7.

Seems like my M7 throttle body has been tampered with by the company I bought it from so I have to redirect my questions to them.

Washers and nut inserts for the Understrut System are on the way.
