Could the fueling issue be because of the old fuel?

[Exmantaa]

No, it's something funny in the ecu. In the log parameters I included the commanded AFR and you during idle can clearly see the ecu switching by itself from a closed loop commanded 14.7 AFR, with the nice alternating 1st-O2 values and fuel trims, to a sudden commanded rich 10.10AFR where the closed loop fuel trims are switched off... Is related to an internal function test the LSJ ecu performs to see if the rear O2 functions well. If it lacks the proper sensor response, the ecu keeps dumping fuel to provoke a rich mixture reading. Some LSj ecu's seem to have this problem and others not, but then not every LSJ owner is monitoring his commanded AFR so closely and have the rear O2 sensor deleted... @ Vocky; the internal function checks are pretty advanced and we're not sure yet what signal feedback is needed for this. So simply fit the sensor in the exhaust pipe and if it works I can log what signal voltages are needed for a sim.

it will be easy enough to weld a lambda boss in place

Joe - buy a lambda boss http://www.ebay.co.u...=item1e6eb426cc

Think Joe is working flat out again and no time for the car... For this testing he just needs to swap out his WB sensor and place the 2nd O2 back in to see what is what..

[vocky]

even easier

Didn't you have nice interior bits?

[The Batman]

yeah but sold them the new ones will be much much much nicer with some stitching that is going to give the colour respray away

[ArticMonkey]

It was epic interior the first time round. What you getting, vibrating seats ?

[The Batman]

if only!

[ArticMonkey]

Is he actually doing anything with your race seats? Extra padding or comfort for them long time attack journeys.

[The Batman]

no i never mentioned the seats

[ArticMonkey]

It's interior is it not?

[The Batman]

Not much you can do with fibreglass seats though is there!

[ArticMonkey]

Cover them in leather or spray them black if your names JG.

[vocky]

any new pics

Sorry for the late reply I don't have Internet at my new house yet

Me and vocky decided to do some ultimate butchering today! And cracked on with 1st fix of fitting the new body kit as I was really not happy with the body. (Then fab helped take some old paint off )

Here are a few photos! Just in time for Halloween

First off, you remember that mint rear clam? Well me and vocky decided to make a vx211



Then cracked on with fitting the exige clam





As you can see its still a first fix! Next time we are going to blend the arches, side skirts and exige clam onto existing paneling then as soon as this 2nd fix is done its then off for a full respray
