Since going FI and remote lund tune I've never really been satisfied with the quality of the map.
It works ok but being a bit of a perfectionist, not well enough I feel.
I have this occasional engine lurch/stumble when tipping in to light throttle, happens maybe 3-4 times in a week.
The idle is high for my liking and when I queried this the revision was awful, had to accept the higher idle and revert back to previous as things were getting heated in the emails. Not the best service I've received.
I feel it's over rich despite Lund saying it isn't. I have black exhaust and lots of black carbon spots on the rear bumper. It stinks of unburnt fuel from behind when given a wot blast and you can see the haze in the mirror.
On a track day, the haze is annoying and embarrassing.
Doesn't use oil or breath so it's not that, just heaps of fuel.
I've smoothed out the Maf signal by smoothing out the pipe transitions and increasing the taper on the reducer that sits before the blow through Maf and made an air straightener that sits before the Maf. Maf signal looks more stable than the stock Paxton setup and Lund calibrated the Maf after. Made no difference to drivability though unless looking at the log.
If I unplug the Maf the car runs like absolute shit so the tune is heavily reliant on the Maf signal and I think that a bit crap. If the Maf died, it runs so rough I wouldn't be able to drive it home.
I've heard good things about Wengerd, what does everyone think about trying someone else?
