MTM chip or MRC ?

6500 rpm in 3rd gear well in excess of the 70mph speed limit

Do you always stick to the speed limits then ?

We always stick to the speed limits on the UK roads! But you can do more than 70mph in Germany and you can do more than 70mph on a track or runway or your own private driveway.

I'm not going to get involved with any arguement about the value of FATS. I am just expressing my opinion. If there are readers of this thread who don't believe that a custom remap is better than a generic remap (excluding the factor of long-term reliability), then no amount of arguing is going to change their mind.

My last point, however, is to remind doubters about what "custom" means. It means tailoring the map to both the specific engine AND the driver's requirements. If for some reason you want an unusual torque curve then I believe MRC can do that for you (correct me if I'm wrong Mihnea).

......similar to buying a suit "off the peg" or having one "Tailor Made".

Yes, but for a tailor made suit you would want to know the tailor is good. I think thats the side the MTM fans are coming from.

Theres more out there than you think.....I went for a remap from Rica engineering www.rica.nl They have branches in the UK, i was offered 2 maps, 1.7 bar and 1.9 bar, i went for the 1.9 and man its good. Under £500 aswel, including basic diagnostics on the day and a good look over the car before it was mapped. Service was A1, the car is now astonishing

Hobsons choice

Interesting. Can someone post some links of these people that have gone from another tuners map to a custom MRC map. Would love to see the dyno chart to show the difference. Why would you want an unusual torque curve, surely you just want the maximum that the engine can produce, unless racing where I geuss you could want special requirements. Can you really trade boost pressure and obtain the same power with just ignition advance.
The only thread I could find was for an RS6:-http://www.rs246.com/index.php?name=PNp ... lling+road

I'd go MTM, I've been in a remapped MTM RS4 and it was awesome with loads of boost starting nice and low. I personally would not want a car that has to be wound up to make it go all the time. This again is just an opinion.......

The rica software is silky smooth, boost comes in swiftly but smoothly, giving more traction. I am going to powerstation soon in tewkesbury, i will post the dyno plot then. My car already had superchips software on it, the difference is almost like going from a stock ecu to remapped again. Any gear and time it seems, 5 seconds from 50mph - 100 in 3rd gear.

Infact i have uploaded a vid:)

Ive had both.... I had an MTM chip in my S4...
I did some testing between that and I personally thought the MTM chip was very laggy.... It was in the car when I bought it and I had a spare std ECU and I swapped between the ECUs...
Although the MTM chip was obviously faster the std chip drove FAR better.... so much so I left the std chip in place until I went the 700 mile round trip to MRC to get a remap from them. I specifiaclly put the MTM ecu back in so they could destroy the damn thing I was that unimpressed with it.... The MRC had far better driveablilty AND the performance. MRC everytime.....

What rpm's does it hold 1.9 bar until ?

Post by **Overlord** » Wed Mar 07, 2007 9:13 pm

No idea, i dont have a boost gauge, there is a power curve on rica.nl, but i would imagine its for the 1.7 bar map. Hopefully powerstation will have a boost graph available for me too see aswell, they have a maha ram 3000 dyno so its possible.

Ahh Mr MRC, is there an issue with 1.9 bar then ?? If so what, will the turbo's not take it ?

I can't think of a better way of assessing performance David T (apart from maybe street racing) but that doesn't make FATS perfect.
Being a VAG COM addict I really want to believe in FATS but things like gear ratio variations aren't accounted for, Ash318 has an S4 and does FATS in 4.0, my RS4 does it in 3.7 but I have a shorter 3rd gear, which car is performing better? Can we at least have an adjustment formula for RS4/S4 3rd gear ratio?
In answer to the question, I wouldn't pay £900 or so for an MTM chip (they've just reduced prices BTW) when MRC's custom remap is so much cheaper but I have got an MTM chip that came with my car and it seems to have no downsides and feels loads sharper than my friend stock RS4.
I wonder how many people go custom only to end up with the same map as the generic option anyway?!

A conversion factor is a good idea. ash's car is faster than yours

I did a 30-130 post in the vag-com forum because it gave a better mix of engine speeds.

I'm not going to bite, David T

Ahh so you had a better performance test already, sounds interesting..
