Motech mapped DSG 'hesitation' after gear change - FIXED. R-TECH Reign supreme
john a:
Understood, when Dynodaze was recommended by R-Tech I did question the accuracy of their dyno and was told 'about the same as ours', so had no reason to further question. I am not informed when it comes to these things, but concur that Dyno Dynamics is supposed to be the industry standard.
Motech do not own a dyno, apparently principally because of the proximity to Dyno Dynamics, they do not feel the need. Some logging was done and the car was found to be doing the necessary, although I doubt that this data was logged as a csv to show the car's behaviour under load.
I have started doing some logging and it is a case of interpreting the data. Once I understand what the cause is, I can look at a solution (whether it's hardware or map).
I'd rather not spend out money with somebody else on sorting this out, if it's not a hardware issue, but hopefully I'll get a response from Motech in the week and we can go from there.

God luck with it, if you need any help with logs, just ask.
Love the reason behind not having a dyno :signLOL:

I think before putting dynodaze down you need to get facts correct. :smiley:
The "V-tec" dyno gives acutally fly wheel readings calculated from wheel hp and coast down losses, it dont guess fly wheel the power like a DD rolling road.. :sick: LOL If you can answer me the question how does a DD rolling road give actual flywheel hp readings?? As IMO a DD rr is only good for TRUE wheel HP numbers? :wink: (well marketed the only reason I cancled my order with Mike @ DD he could not show me how the system worked out the trasmission losses)
The picture on ebay is the base line model for £12k, inerita only pc based, the one dynodaze use has the full controller with 128 input highspeed data logging. It works really well and give correct numbers and graphs by using raw data, not fancy algorithms like thr DD to work fly wheel hp out.
Its a very good rolling road setup, its unbias as dyno daze dont sell remaps or software they just do rolling road power runs and logging and rent out to tuners to fill a void in the market. It reads simalar number to my Bosch dyno +/-2hp and about bang on wheel HP as the two DD rolling roads I use, the only variation between all four dynos is the reading at the fly v both the DDs. The reason I send people to dynodaze who want to there cars tested with other tuners map is to get rid of the bias factor. If there are issues then we will take on the added logging work to find faults.
All of my rolling road days are now ran on the dyno daze rolling road so I dont get called bias... If it was crap I am 100% sure I would not put name name aginst it.
You will find a lot of maps which aint setup on a dyno feel good on the road but dont offer the smoothest graphs, a dyno at the end of the day is a tool to aid tuning and to gain a visual picture of whats going on.

i was always under the impression that DD rollers apply a set transmission loss set from a database. This is why its WHP that is accurate on the DD rollers and not Fly Hp as it doesnt take into account how tight its strapped or tyre presures etc. What that does mean though is DD rollers are consistent between cars at different DD rollers.
Others such as MAHA and Bapro rollers for instance use the coast down method to measure the actual losses.

Good DD ops should give reading both at fly wheel and wheel, when I use the 4wd DD dyno I always give the readings of wheel hp and fly hp. On my dyno I give the graph with wheel hp curve with losses at the bottom to give a measured fly wheel hp reading.
