Hmmm, thanks Dan, but I'm still not exactly clear on what it is. Would feedback exist if you were just boosting off the wastegate spring pressure, or is this a condition that exists exclusively when using a boost controller?

Maybe some experts can chime in here but I wouldn't think it would do anything if you were running off wastegate springs since thats what controls how little/much the wastegate is open.

Where do you tap the intake system for a MAP sensor reading and where does your boost solenoid tap the turbo outlet for boost reference?

Closed loop takes input from the MAP sensor to regulate the duty cycle for the boost solenoid, which rapidly alternates between free air and boost reference and "shows" that to the wastegate.

What is wastegate pressure for you and are you internally or externally wastegated? If it is low (safe) enough, trying wastegate pressure is not a bad idea for troubleshooting... The Haltech will still be able to work the overboost fuel cut safety.

In closed loop boost control you set the target boost and it does the work behind the scenes to achieve/maintain the target boost.

Open loop is more like an advanced manual boost controller. A percent duty cycle is set for the boost solenoid to operate at. This can be constant number, or a table with configurable axis (rpm, wheel speed, etc).

Does the boost spike when running on wastegate?

What's the best option to controll the boost, using the Haltech or Greddy Profec E01? Or both?
Can the Haltech be used as a base and the E01 on top like "over take boost"

I actually haven't tried running it on wastegate pressure but I'll try and report back

I'm at my tuners shop right now and the same problem here, but it dosn't work w direct x 9c so rally need help now!!! PLEASE!

PM Hal@IP. Pretty sure you need to just download DX9 from microsoft, install, reboot, and you should be good to go...

350zzzgunnar

Had to install a US XP OS to be able to run the software. But that did it, so now the first tuning is done @ 14 PSI (on the safe side) Gona tune again next week for high hp.
BTW its whp.

350zzzgunnar

Now I need to install boost controll solenoid and wideband lambdas today so I can take the car to the seccond tuning for high hp. I'm not shure how to hook it up and calibrate.

Should I route the hoses from WG's bottom to one port on solenoid and the ones form WG top to a seccond and the third port to vaccum?

As I have 2 Innovate LC1, I think it's 0-5 volt for 7,35-22,39 AFR.
I guess I just have to input these corection valus in the Haltech EMU for Volt and AFR's???
Anyting else?

So, is the knock detection/control software update availible yet?

Dynosty

iTrader: (27)

Knock detection - yes, it has been in it from the beginning.
Knock control - sort of. You can set one of the ignition modifiers to retard upon knock. Actual knock retard tables have not been implemented yet though.

Will the ignition modifier add back the timing once no knock is no longer detected? Is the modification permanent? Is it done just at the knock location in the maps or is it global?

Dynosty

iTrader: (27)

Yes, normal timing will resume when knock subsides. Setup on a user-defined knock scale, it will pull more timing for more extreme knock. Also the knock threshold is completely tunable on a x/y axis map to eliminate false knock.

MR RIZK

what is considered a bad knock. Once you have tuned the threshold table as per the instructions and notice knock on the K Level D (RAW) display, what is considered a high value. ie 50,100,150 etc

On a side note I think the older software was set to 0-500 for Knock Level D but now is 0-200 where K Level L is 0-500 so is 150-200 considered bad etc?

Dynosty

iTrader: (27)

Once the threshold is calibrated, knock should sit right around ~0 under normal non-knock conditions. Then a knock count of 0-10 I would not worry about as it is probably noise. 10-50 would be start of knock, and 50+ being serious knock. It is easiest to monitor using a trace view, where it will have noise bouncing around the very bottom but you will see large spikes in the trace if knock is encountered.

gecof1

Yes but how we calibrate the threshold? There is nothing mentioned in the manual. What is the nominal values that should be used on the conservative side for the map? Do we have to do that on the dyno, by hearing the knocks?

Dynosty

iTrader: (27)

Use a safe/conservative tune and watch knock level. Whatever is coming across at that point is noise and should be put in the threshold table so it will be filtered out.

Hi Hal/IP

I need some help!~

Any idea where can i get the new firmware for the platinum ?
I install mine today but the software seems have problem,
on the tuning map it has 2d and 3d map table. But the 2d map table all are shown with C C C C C on every table. I try to play with the injector trims it seems that it dont work. Is that possible there is bug on the ecu manager software ?


Also I have the innovate LM1 , I would like to wire them up so i can view the afr in the software. could you guide me which socket or wire to input the 0-5v wire to the unit.

Then I also notice the haltech ecu are very hot!~ . it is too hot to touch.

PLease email me if you have any idea why.

Thanks

^ A cell with 'C' in it allows the factory values to pass through. The C stands for copy-through. Pressing "c" while in those cells will take them out of copy-through mode and give you control.
