I have read a lot of the posts about Guzzidiag etc and have gone and bought the cables etc.
Good news is that, following Beetles directions, i have connected to and downloaded/uploaded the .bin file etc using Guzzidiag.
It all works great.
I have the cables from Lonelec
Everything worked first time without any issues
I have modified the speedo correction, using Tunerpro, which is great.
I have reset the TPS, each time, after writing to the ECU.
Does the TPS need resetting if it stays at 4.7 after writing to the ECU?
When doing the TPS reset do i need to get the engine temp to a specific temperature, or can it be done cold?
I did reset the TPS and now it stays at 4.6 no matter how many times I reset it (was 4.7 originally).
When would you reset the auto-learning parameters?
Can someone point me in the direction of the posts involving turning off the Lambda sensor and why?
I'm not keen to modify the tuning parameters myself, I'll buy one of Beetles maps if I decide to go that way.
The standard map is very flexible around town, might not be as strong as it could be on the open road.
