Old Tuner File Review, and a few niggles.

when not on full throttle but still accelerating at some points through the rev range, it seems to hold back then kick in again then hold back , like someone is taking away the power very slightly. never did it with my std file. some days it worse than others, noticed was worse today driving through a very cold spot ( fog near river etc ) ..

will the update Sort this out? i would sacrifice a few HP to get the car more smooth.

also anyone notice with all the files at mid revs it seems to accelerate itself?

and engine & gearbox wobbles at full throttle at end of rev range?

MTH people / experts , please shed some light on this for me.

And i have a graph from a rolling road from my old std file and my mods are viper induction kit magnacore leads and upper engine powerflex insert, along with MINI's Sport exhaust (not high flow or anything).

Thanks Guys

Can you explain more with what you mean by it accelerate by itself. You mean the car acceletares without you pressing the throttle?

Engine & gearbox wobbles.. You mean they vibrate and sound terrible?

"You mean the car accelerates without you pressing the throttle?" Yes it does, at a point in the rev range i can keep my acc in same position and it will accelerate by itself. try-ed several times just to make sure it was not just me.

I have my gearbox cable system changed as it popped itself off, ever since it seems to wobble, booked it to sort that out, don't think it would be a engine prob, as i did not like the behavior of the MTH iv decided to Waste 300 euros! car has a yo yo affect about 4000 rpm, and does not run smooth. iv e-mail MTH, Taken a week now and still no update or answer.

so like i said car back to original, until MTH Can fix my problem. if they ever get back to me. all they have said is they are busy.

etalj :
i too have the stutter... 2 to 3k rpm, its not too bad. I also know what your talking about when you say "accelerates itself." At about 3000-4000 rpm, for the same throttle position, there's a sudden change of power delivery. It doesn't seem to lag at all, and it's as if you're putting your foot down a fair bit.

Ok, I don't think my car acc by itself or maybe I wasnt aware of than. I'll try it out later.

However, I do have the yoyo / lag/ sudden change of power at the range of 2k-4k rpm and I believe most of the Tuner users are suffering! It seems like the car is not that smooth like the standard file and i agree that the engine is vibrating at full throttle at end of high rev, lets say 6K rpm.

Volker, can you do something about it? Or at least update us with the new progress? I've been waiting for almost 1 1/2 week to get the V7. Are you ignoring the old users and give high priority to the new registered users?

Does anyone elce have these problems, i am not using MTH till i know this problem is fixed.

What are the reasons behind the faults?

[minionefun]

yeah but whats the reason why ppl are having these problems?

[MINI-Morgan]

I'm confused by the car pulling harder at 3-4,000rpm... isnt that normal?? When u enter the real power band the engine will pick up and the power delivery curve will then become steeper, so delivery ever increasingly more power until the rev limiter??

Yes, we can. VT7 is the way to go. It took us a while to reproduce the flat spot on our cars. Out of all the MINI´s we did, only very few had the flat spot. So that is/was not a general problem.

We get flooded with vt7 requests, so it may well take a bit longer than usual to do those upgrades. Besides that, we do have our normal day to day work. And it is definitely a NO that we ignore the old customers. That has never been and will never be the company policy of MTH. After all, where else do you get free updates and service even over weekends?

So please be patient, we will send vt7 to all of you that sent me their request. Thanks for your understanding!

hey volker, does the flat spot get fixed automatically? or do you have to let MTH know that you have the flat spot, and then they fix it...?

The new vt_7 file DOES fix the flatspot...if you have the flatspot then send the MTH file to Volker or your MTH Dealer, with your current mods and what RON fuel you are running (eg 98RON) and then a new vt_7 WILL be sent to you in due time.

I would suggest only people with the flatspot ask for new files at this time. Owners with the file and no problems can get a new update at a later date (still FREE OF CHARGE) from myself OR Volker. This may help with peoples problems regarding how long it takes for new files to be returned.

Charlie...

I hope our conversation on saturday cleared some thoughts regarding the MTH and your gearbox faults.

Elie, where abouts in the rev range is your flat spot? I have the new version and it didnt fix the flat spot for me, just made it less harsh but it now lasts longer, which sucks. I dont even drive the thing like this. Might have to look for a alternative tuner but we dont really have choices here in Oz do we!!!

less harsh but lasts longer ? have you also contacted your MTH dealer to say you still have problems ?

[XTREEM]

By less harsh I mean it isnt as savage of a power drop off as it was on the older file, It seems to be feathered out a little, but still goes off power at around 2800rpm and doesnt really recover until redline if at all.
With the old version it was a much more harsh drop off. At 2800rpm it would drop of power really bad but would come back on song at 4500rpm. Now it doesnt come back on song.

I contacted Volker straight away after the first test drive and got a reply on the 20th Nov saying he would work on it.

Bye the way there are some people on the forum who believe my problem is not MTH related, but I never had any signs of this before upgrading to the race version with 380cc injectors, it then got worse with the tuner file. And when I go back to the standard MTH file the problem no longer exists.

my flat spot is around 2500 rpm. I've heard that AMD one-click was good, but yeh exactly, we don't have a lot of choice . You're mods shouldn't have any effect on whether the car has a flat spot or not anyway, as you're running as smaller pulley and basically works injectors, and that doesn't have the same flat spot. What might be best for you is maybe a GT Tuning style ECU remap, where they upload info and remap the ECU while on a dyno. Dunno who might offer such a thing in aus tho. Keep us posted.

i thought as much.

by the way, does your flat spot happen in every single gear? I get mine most significantly in second. It's a tiny jump in power at about 2800rpm.

Elie

[Cooper_si]

Ive just done a vt_7 update on one of my customers cars and taken it out for some LONG driving....cant fault it at all !! And thats through every gear !!

Alls good

Yes every gear.

[Boyderama]

Hi Simon,

When I get the update and indeed buy the leads, would it be advisable to reset the ECU and clear out my driving style?

Thanks,
Boyd
