Hello Guys
Not really sure on where to start with regards to asking for help however after browsing the site its clear people on here know what they are going on about!
In essence I have a MK2 GOLF - 1.8T AGU conversion with a M3.8.3 ECU 6A906018CG
It was previously mapped stage 1, however had no hard cut or overrun so wanted to spice it up a bit!
I have MPPS and have used this to write the 2 files below which I paid for, however both are not very good at all!
They cause the car to lunge forward when coming off the throttle and the engine does not respond for several seconds after changing gear.
It did not do this before! It also seems so much slower than before there is something seriously wrong I belive.
I am wondering if anyone can help me with a map, or if they have a tried and tested one I could use.
I am looking for a stage one map, with light crackles on overrun over 4k and a hard cut that sounds like https://www.youtube.com/watch?v=mT_MgUUKyBc
The car is running a manual boost controller set to 1.3bar and has no lambda.
I know this is a long shot but if anybody has an interest in these conversions I would be happy to provide updates etc on anything I get!
The way the ECU is I have been unable to read it and preseve my original file so I am in a bit of a pickle!
Thanks for reading!
