Belchy Posted February 19, 2005 Report Share Posted February 19, 2005 As a follow up to the AMD remap on my A3TQ just before christmas .... Car is running lovely however it sometimes gets a bit jerky when short shifting gently. Seems as though the turbo cant make its mind up. Its especially noticable when cold. Also the fule consumption has gone from 27.5MPG to 25MPG on average. I have noticed that if I have the cruise control on and stay at 70 on a strech of road that I regularly use and set the DIS to display the "live" mpg, its noticably worse than before I had the remap. All this said, I am very pleased with the extra performance as it now goes like a train compared to before and would deffo have it done again.

shao_khan Posted February 21, 2005 Report Share Posted February 21, 2005 The mpg suprises me - my TT remap with AMD the mpg was significantly better when cruising with the control set at 70 - over 40mpg on a long trip. Link to comment Share on other sites More sharing options...
Mollox Posted February 21, 2005 Report Share Posted February 21, 2005 Smoke, You might have a potentially dodgy MAF...just changed mine and I'm surprised at the effect it has on the whole engine's behaviour Link to comment Share on other sites More sharing options...
Belchy Posted February 21, 2005 Author Report Share Posted February 21, 2005 Performance wise its spot on ... no flat spots etc.. cars only done 17k and is 2003 plate Ive noticed that a friends imprezza wrx does the jerky thing when shortshifting. It does it when using (for example) 10% of the throttle travel and gets to around 2k rpm. You then release the throttle to change gear and then the jerk happens I drive it very gently like this when its cold Its like the turbo jerks on and off. When driving the car enthusiastically, there are no jerks or flat spots anywhere Anyway I'm not too bothered as its a very minor niggle considering the pluses Ive got from the remap. I'm a bit jealous of Shao Khans finding with the MPG though Link to comment Share on other sites More sharing options...
danksy Posted February 21, 2005 Report Share Posted February 21, 2005 I never managed more than about 35mpg on a long run when remapped in the TT's . When I sold the TTC I averaged 28mpg, when I sold the TTR I averaged 26mpg. Link to comment Share on other sites More sharing options...
shao_khan Posted February 21, 2005 Report Share Posted February 21, 2005 I suppose I should add I could get over 30mpg with the R32 on a journey. Link to comment Share on other sites More sharing options...
Insurance Jon Posted February 22, 2005 Report Share Posted February 22, 2005 I vote for the MAF issue too, it sounds just like the 3 I've had go on different cars, it gets more obvious when you map them. Link to comment Share on other sites More sharing options...
Chrisg Posted February 22, 2005 Report Share Posted February 22, 2005 regularly got 37 mpg-ish out of a remapped A3 T Sport more on a longer run and I averaged high 50s mph. Traditionally remapping these cars gets better mpg. Link to comment Share on other sites More sharing options...
Belchy Posted February 22, 2005 Author Report Share Posted February 22, 2005 Hmmm ... maybe I should put it into Wayside for a fettle. Link to comment Share on other sites More sharing options...
Tomk Posted February 23, 2005 Report Share Posted February 23, 2005 mpg after a remap on Tsport ???? on my tsport im now getting about 30-33 over a tank... what am i doing wrong ? on the motoway i get around 35-37 as long as im gentle and dont go over 80 Link to comment Share on other sites More sharing options...
Thorney Posted March 10, 2005 Report Share Posted March 10, 2005 Sounds like a MAF to me. MPG will settle down after you get used to it, on my TT it went down then up....however on the RS4 it went down and continued on sprialling path to financial ruin (mainly due to track days ) Link to comment Share on other sites More sharing options...
Belchy Posted March 10, 2005 Author Report Share Posted March 10, 2005 I went to coventry the other day and decided that I would see how good the MPG was when driving sensibly. I reset the DIS and set off... I live 2miles from the M1, so within a couple of minutes I was on the motorway with the the cruise set at 70. With clear roads all the way (sunday morning) I made it all the way to Cov and back with a mixture of 70 and 60 mph, all on cruise control and very light acceleration. (No sitting in traffic etc ...) At the end of the return journey, the DIS showed 30.5 MPG average. Does this sound about right? Also, is it likely that the MAF is faulty on such a relatively new/low mileage car?

steve2 Posted March 10, 2005 Report Share Posted March 10, 2005 i would have thought that you would get mid 30s at least Link to comment Share on other sites More sharing options...
