FSP - IPF Supercharger Installation Thread..

[Nutbutt]

Seems to be the base file that IPF uses, I believe it is a Bosch file. Don't believe the other use the original files.

They should have de-sensitized them a bit because of the S/C mounted to motor you will always have to remove a bit of the threshold values.. However, I have been informed that all the functionality of the knock senors are installed.

False knock.. Ya, OK

I had to data log at same time and review to see the knock happening.

I am not logging cannot log KR with my software I could only log commanded timing which is all but useless...

However, as I listen to every motor on the dyno I do not hear anything audible nor see anything in the graph to indicate knock. You get an ear for this stuff after 14 years :P

All I can tell you is that mine is a friggin' beast and everyone driving an LLT/LFX ought to get this done.

And no one can even tell. Except for that whine/whistle/jet engine sound, that is.

The graft on the other post had a run from stock and both tunes. And none had the crazy waves or false knock.

I know on my n/a always get the waves even on different dynos. And the waves don't match with the knock the eng is detecting when I review the logs.

Maybe you just know how to do the dyno better? Lol

Just trying to understand that wavy graph some of us get and others don't. And your dynos don't have it.

Ok this kit is the one at top of my to get list. Just so many things good about it. I just want to see my number 2 option once :-(

Nice numbers Matt, I see mid 400's on a dynojet with this set up.

Loveing this thread.

I can't wait to see more dyno information, videos, and pictures of the car.

I'm betting this car sounds BOSS with those headers...which by the way I'm sure is adding a nice bonus power.

The program will ask you to get your car's ICU info, so you then unplug it and go to your car and plug it in to the OBDII port (always plug in/unplug the device when the ignition is off) until the light on the tuner goes solid green, then take it back to your computer. The list of available tunes comes up, and following IPF's suggestion, select the appropriate tune and allow it to load into the tuning device. Again, take the unit to the car and plug in and wait until it loads the tune into the car's computer. Done.

Make sure all accessories, including automatic headlights are turned off when using the tuning device. You want full voltage from the battery available while using the unit. The ignition is switched to "on" when gathering info or loading tunes, but always switched off when plugging in or unplugging to/from the OBDII port.

Send the darn thing back and get your deposit back. Enjoy marked increase in acceleration and increased rear tire wear.

Excellent info. Your posts gets the KMPrenger approval! lol

Nice job Matt!!

The wavy lines are probably from either knock being pulled, fueling off (AFR sweeping back and forth), or not enough spark (Whether or not commanded advance high enough, OR spark blowout)... This is general.

I don't recall seeing an IPF tuned system have this issue (correct me if I'm wrong), so obviously they have a different tuning approach than the other systems out there. Some say it's because IPF is based out of Europe and so is the Bosch ECU.

Hi !

All modern Bosch ECUs are controlling and limiting the max allowed combustion noise ... that has primery nothing to do with the knock control .. but both control systems were using the knock sensor input !

as the knock sensor is a piezoelectric contact microphone system ... it detects not only the combustion knocking .. it is also measuring the combustion noise ( level ) ... and that level is at 300PS lower then with 4xxPS SC Kit !

And that mapping is ALL done in the software of the ecu !!

also it makes NO sence to switch off the knock control ... because thats an engine safety feature that we dont want to miss !

regards and good night at 03:24

Correction; 3:25 your time... Ash you are a trooper, it's been a pleasure working with you so far and we look forward to working with you a lot more!
