MANUAL GEARBOX

[chunky79]

I'm using the grizz gear box map - which I have mixed feelings about.

How come??

[gingertoss]

I've got the mrc box map. In tipro it stays in what every gear you selected when you floor it, it does not down shift without you telling it to. It will down shift by itself if you are coasting down to traffic lights and the engine rpm is down near 1000.

[Shoppinit]

No, with the MTM TCU tiptro it won't kick down whatever you do. The only time it will change down is if you go below 1000rpm to stop you stalling.

I'm surprised you're having issues on the motorway. When I want to overtake I accelerate from 70/80 I just press the accelerator in D. It only kicks down if I accelerate hard or put my foot to the floor (kickdown switch). Again, in D. In tiptro it won't kickdown.

If your car is remapped and it is hunting between 4th and 5th when pressing on, then the TCU isn't right.

Only as old as the woman ya paying for, eh?

Doesn't make me much younger unfortunately!

Fortunately you're far more decent than I and thus missed my point. I was referring a different kind of woman, you know, the kind that you pay to leave after an hour, not the kind that stay with you 'til death do you part.

After more than 20 years in the city, the point was not missed...

Genuine lol.

Might I suggest even younger women and instist they not call you daddy. Never really understood that, methinks those girls may have had some 'issues'.

Same here. Although if your engine has been mapped and has silly amount of torque, the box may have also limits as to how much twisting forces she will accept at low engine speeds. Knowing the inherent weakness in the box, why would you want to make it go through that sort of stress when a simple pressure on the "-" paddle gets the job done faster and is easier on the transmission? It goes back to D on its own after a few seconds anyway.

[Shoppinit]

I don't agree. I believe that gearchanges under high load are much harsher on the box than accelerating in gear with the TC remaining locked. Or even if it unlocks. There will be less wear on the clutches which is what eventually renders the box useless.

[monoi]

I do not know enough about the way this box works to argue one way or the other. However, I did not mean that I put my foot down and then downshift with the paddle, I downshift 1st and then put my foot down (rarely all the way either). That will definitely put less stress on the box, doesn't it?

[Shoppinit]

I think it's pretty much negligeable either way. What kills the box is full power gear changes, standing starts, making it work hard when not up to temp and not servicing it. Doesn't help that some have weak parts in them like a time bomb waiting to go off - dodgy oil seal in TC, brittle ATF pipes...

Change gear, don't change gear, ultimately it's a drop in the ocean in terms of wear / stress on the box.

What is sure though, is that if the TC doesn't unlock when accelerating then there will be nothing inside the box that will wear since nothing is slipping against anything else. I can't remember if the TC unlocks in tiptro when accelerating with the MTM TCU. I am 98% sure that it doesn't, but I would need to log the box again to check.

[Mr Footlong]

I wish I understood half of that stuff above, but I don't. Therefore, I will just continue to drive it until it breaks and just get it fixed, tougher. I will give the paddles a proper go but no promises I adapt to them and nobody to blame but myself if I don't .

[MEV]

The remap of the box seems perfect as its the downshifting when not required or wanted on motorways ( as people have mentioned) is really annoying. I like the car to pull away in the same gear sometimes and experience the full torque when perhaps Im nursing a coffee or patting the back of some young felines head with my left hand It can be so bloody annoying, dangerous and messy otherwise. So whats the main difference between the two ( MTM & MRC) in practical terms and what sort of price comparison are they?

[yorkrs6+]

Theres enough torque in this car to see it go from 80 to warp speed without it having to downshift in the process - id be very happy to press the go faster peddle and for it stay in that gear without any downshift - even if I bury the pedal in the floor - but on mine there is point of too much gas which causes it to downshift regardless of gear (no in D)
Compared to other autos - it would simply hold the gear and give you the torque and pull away nicely. It's not like I'm stamping my foot down - simply applying a bit more pressure to reflect the speed I want push on with.

also if I want to run it to warp speed - there comes a Point where the drag on the car causes the box to down shift - about 120 ish - unless I have several miles of run way the only way to keep it in 5th to get to warp speed is by a gentle fethering of the pedal. Anything else it downshifts to 4th and hangs onto 4th until 160ish and puts up a real fight about dropping in to 5th.

can you see why I don't like the box!

[Mr V10]

Why don't you take it back to Grizz and get him and Viper to sort it? You've been having this problem for a while now and it isn't going to fix itself, Grizz is a good bloke and will see you right. In the meantime, I'm getting the MRC ECU & TCU, as I've done a lot of research and spoken to people that have run/driven every map going on the '6 and all say the MRC code was the best of the lot.

To be fair, this is because your car is remapped and the TCU hasn't been modified to suit. Standard cars don't do this.

[Mr V10]

I'm sure Mihnea from MRC said somewhere you can't map these cars without doing th TCU, and he knows his stuff with mapping.
