Lee said the same.

Looks like a mandatory mod for the harrops on Dutch.

 

 

sigh... I thought I had all shiny bits required, best call the Batman!

U.S. chaps complained it was twitchy, didn't find it so at all, worthwhile upgrade IMHO

 

The dutch running on HP tuners had the same.

Looks like Peter has got that area better sorted. 

 

 

Never tried an LS4 TB on the TPTuners/LSJ ecu, but some US guys said the above.

Will try one soon on my engine.

 

Curious to see some graphs before/after, as the bigger TB will give a lot more air @ mid throttle, what can give the impression of big power improvements

Wanna borrow mine?

Can´t use it anyway till you fixed my harrop.

[Exmantaa]

Don't worry, I'm getting my own J-TB.

[smiley]

If lee´s tuner can get the map sorted, then i´m sure you can do the same I HP tuners.

Maybe the US comments are just poor hearsay.  

[haggi961]

I've got the ls4 to fit soon so will try to do a before and after.

Much better from cold, old map could be a bit finicky I found, no problems so far.

Just changed my wideband for an updated PLX gen 4 unit. PLX now use Bosch 4.2 sensors I am wondering if I need to make any changes to the OBD software for the different Lambda? anyone using this new sensor?

 

old settings EGR input low 00.00-10.00, EGR input high 5.00 - 20.00 with a 170ms sensor delay

 

new one shows measurement range 10-20 AFR 0.68 - 1.36 Lambda   form the info sheet

 

I decided against a gauge in the cabin so just hooked up through the ecu.

Isn't the LSU4.2 the old type sensor and newer ones are the LSU4.9? Both the Innovate and 14point7 widebands I've got use 4.9 sensors.

Does the info sheet tell you what voltage the wideband controller outputs at 10AFR/0.68lambda and 20AFR/1.36lambda as that's what OBDTuner will need to know. ETA: Looking at the graphs on the PLX site, the settings are the same as before regarding voltage. Linear output at 0v for 10AFR and 5v for 20AFR. http://www.plxdevice...?id=SEMOSMAFRV4

Your right Matt the box said Gen 4 PLX ( A white sticker) with LSU4.9 but all the paperwork is for a gen3 unit, not a happy bunny just got off the phone, its a mistake from the USA send unit back....... Just put the undertrays back on AHHHH

[NickB787]

looks like it's sorted I have a lsu 4.9 sensor so just need to try it, will try your setting Chill, what effect does this have on reading?

[CHILL Gone DUTCH]

As long as the voltage matches the output (AFR) it shouldn't have any effect Can you download the setting for the sensor you have You also need to have the sensor delay time

[CHILL Gone DUTCH]

Which sensor did you get in the end nick

[NickB787]

to cut a long story short PLX have been running the Bosch LSU 4.9 since their gen 3 went out but for some reason they still called them LSU 4.2 units they were however bosch 4.9 units I went and checked the Bosch s/n's. I had a gen 2 which was a LSU 4.2 so my setting will be incorrect for the 4.9.

[CHILL Gone DUTCH]

are the right settings available

[techieboy]

Yes, the voltages vs AFR settings are as they were originally. Just the sensor response time that is unknown.
