full load increase electronic governor
I did a little more testing on the way into work this AM.
The added resistance on the rack position feedback circuit definitely makes it a different beast to drive...in a good way.
I'd suggest for a more 'refined' experience that folks incorporate a microswitch on the TPS so that it engages at 75% or maybe 100% throttle...or maybe a Hobbs switch to engage above a certain boost pressure. I say this because if you leave the switch on while going down the highway - it runs a little rough if you let off the throttle at say 65 MPH and get back into it. The poor ECU is having a hard time figuring out what in the heck is going on. I like to have the switch on at stoplights - she comes out of the hole nicely with a little extra fuel. I don't think the added fuel is to the point where EGT's are hot or boost is too high...but I have no way of checking yet.
The rough idle never stopped me from leaving the switch on quite a bit on my TDIs...and won't stop me from doing the same on my Merc...but I wanted to relay the information for those wishing to do this on their own cars.
In the daylight, the puff of black smoke when you snap the throttle in neutral/park is pretty minimal. I need to find a way to 'improve' that.
What do you want a video of? It's not a tire shredding beast all of a sudden - just a little quicker.
Beers,
Matt
