Remote access tuning of Fast XFI ?

[waynieZ]

Ok all you professional tuners out there ,do you think its possible to tune a fuel injection system using the remote access programs they have for diagnosing computer problems ? It should work you have access to the laptop connected to the XFI. The driver can drive the car the way you need to tune it, and you will have the screen from the ECU on your computer . What ever you change on your computer will do the same on the lap top. I know it can't replace the dyno but for drivability shouldn't it work ? I guess you would have to have internet access through your cell phone to do the driving part . But for cold and warm start up adjustments . Instead of having the car at your shop it could be in the owners garage connected to the lap top for your adjustments. I wish my car was ready so I could be the guinnie pig. Or is this wishful thinking?
Let me know what you think. Wayne

I've tried it just to try the feature... it works just fine.

However, for a lot of subtle behaviors nothing beats being there to hear, feel, and smell the thing and drive it yourself. A lot of quick transitional tune issues are tough enough to narrow down when driving. For base VE table steady state tuning, idle tuning, tweaking based on datalogs, and things like that it's not too bad doing it remotely but other stuff like AE parameters and the occasional reversion conditions / very certain condition driveability problems are always best done in person... at least for me.

Wayne --

Take it to a "steady state" dyno... where they can "drive" the car at various loads...

When it's where it should be on the dyno -- get the tuner to do a drive and tune session - you drive - he tunes... Go up hills -- slow and lugging - trying to find a "hiccup" spot - go downhill coasting -- so he can pull out the fuel in those situations (eliminates popping etc)... THEN -- it's got to be checked for cold start / hot start etc... RUN from a shop that just wants to do WOT pulls!!! That ain't tuning!

Let me sum up by saying -- if you have a good tuner (great is better!) it should run - start - drive - just as good as your brand new factory car.
THIS is the beauty of EFI... I don't care what anyone says about their carb'd car... nothing beats EFI.

AND -- one more "PS" -- these systems are all similar - A/F is A/F - but try to find a shop that is familiar with YOUR system... there are so dang many variables and tables etc. It's like a MAC guy trying to fix your PC... he can probably do it - but I'd rather have a MAC guy fixing my MAC... assuming everything else is equal.

Just my .02 -- I've spent 10 years with this stuff and been through the growing pains of systems and "techs" -- and there's a HUGE difference in shops trying to do this stuff. Some are great - and some just flat suck at it! :rolleyes:

WaynieZ,

I used to work at a dyno shop (New England Dyno and Tuning) there are a couple really good shops in MA that can tune the car for you.

[waynieZ]

Thanks everyone, I didn't know they used remote access. Story of my life a day late and a dollor short lol.
96z28ss I would appreciate a list of them please. But I'm a long way off from installing my XFI .I need to get the car back first...
What do you guys think of MSD injectors? Theirs a guy who has some relatively new 50lb MSD's for reasonable money . I was thinking of getting them for my set up.
Thanks Wayne

How much power do you anticipate? The 50's might not be enough.

I've used quite a few MSD 50's. They're fine. Have them cleaned or at least run on an injector balance test before you install them.

[waynieZ]

The dyno sheet from the motor was 600hp.

[ivmotor]

That's right at the number. Get em.

Bud at Redline Weber EFI tuned a KHI "T-Rex" from his office in S. Calif, the Quad was at a track in Kentucky.

Another feature for this to work was the "wireless RS-232" interface@19,200 baud.

A Quad has NO room for even a laptop, the good news is this is low cost system with about a mile range.
