I am a VW APR dealer and have had nothing but problems with them and now that Holley owns them it is terrible... no customer service whatsoever!
can they do remote tuning with these? When I did it I had to grant him access to my pc through an app that allowed him to make see what was on my pc live and make changes. Or do you mean through datalogging and sending that data back to them?So I have to ask, are you planning to go any further with mods or boost, or are you wanting to correct the car and enjoy it? If you aren’t needing a dyno tune, then it would only make sense to get a good remote tune done because if you change Tuners right now you’ll have to buy the handheld and pay for a tune. You already have this handheld.
I would give this company a call or email and see if the can make the corrections that you want and ask them if they are going to make adjustments based on your datalogs. If they tune on your logs, it should work out fine.
just curious have you failed emissions already or is someone telling you that you will fail if its rich?
I can't remember now if we have done this already but I don't think we have, have you pulled a plug to check and see what is happening over all in the motor? I say this because the car is not going to run at perfect afr at all times as some places in the rpm band you want it to run a little rich and other areas slightly leaner and over all the motor is happy with tune. I don't think I have heard you say anything about it running bad, just that the tuner is showing its rich in a certain area and it might not be a bad thing. It would take 5 mins to pull a plug easy to reach and a quick look at that will tell you if your really running rich or lean.
I’m pretty sure the Diablo sport doesn’t have live tuning capabilities. You have to load a tune and log it for the changes.can they do remote tuning with these?

I assume your swapping the injectors because of the tuner showing the trim was off a little? Was there any problem with how the car ran?
Yes the car had a pro charger fitted when it came over from the states and had a tune on it. In the states the tuning garage used the diablosport program to set it up. I no longer have that tune now due to the diablosport tuner crashed on me two years ago and had to be fully reset and loosing all the tunes but diablosport did help me out and resend me the N/A tunes again.
I’ve hardly driven the car due to this over rich condition cause I still believe that’s why the original engine with only 42,000 miles on it broke. Number 8 cylinder wall was very badly damaged and I was told it was damaged this way due to a lack of oil on the cylinder wall
gotcha. Try the smaller injectors I mean 2.5lbs doesn't sound like a lot until you realize its a little more than %10 bigger. Now one of the other tuner guys will need to confirm or deny this but I would have thought the EFI was tuned correctly and running right that it should be able to adjust that much to correct for it? It makes me wonder about your oxygen sensors. What exhaust modifications has been done to it short of long tubes and removing the cats (I just saw that). Are we really running no cats and wondering why we are failing emmissions?All plugs are black and sooty, my O2 sensors are only lasted 12 months on average before they go bad and when I pull them they are also black and very sooty. Last year the garage spent 16 hours trying to get it through the emissions test using every trick they knew. The analyser was reading rich from idle (it was very rich) all the way up to 5,000 rpm where it started to lean out, NOT go lean but started to lean out from the over rich condition. we swapped in new pink top 21.5 lb/H @ 40psi injectors and they made no difference at all. The year before that I had the exact same problem but on a different engine running the same pink top injectors. My mpg in town are between 8-9 mpg at best. On the motorway I’m getting 180 miles on a tank which is around 11.5 to 12 mpg.
they fitted a wide and to the car and went for a drive and got a reading of 10.7 at WOT, at that point they dropped the car back off at mine and said that I need to solve the over fuelling condition :-(
Aso on a cold start up the exhaust smells of fuel but when the O2 sensors wake up that smell does die off.
I’ve tried using the stock tune, diablosport 87 tune and their 91 tune and although you can definitely tell a difference in performance all of the tunes run rich
