Did you ever sort anything with the idle target AFR going to the closed loop value?
Re tuning my car with new engine combo and noticing something very similair.

Can have it idling from 10deg to 90 deg all in closed loop idle. As soon as it hits 44 degrees it jumps to 14.7 for a second. When idle AFR Is around 13.5 at that temp.

Yeah I did sort it iirc. Some table at 44c for 2 sec. Can't remember what the table was or what value I put in.

yesterday I drove the VP, first time for ages as I was interstate for work. I kept hearing to clanging at the back and the engine lacked power. Took ages to get to 80 and wouldn't go much over it without heaps of throttle.

Found the tail pipe was hanging by a thread as the metal on the muffler had fatigued badly, cracks every where and it looked like new still. had the sticker on it and all.

Lucky I had the vacationer still so I raided the rear section which I bought back in 07. After taking off the old one I found the guts had totally broken apart (welds breaking not rusted out) So that must of blocked the exhaust and killed my power. Geez has it woken up now lol.

Must of been some shit brand that just fell apart.

yeah I had the same thing happen to a VR V6, the internal baffling rusted out and blocked the outlet with only small holes, was ok till be about 3500rpm then just choked, and had a good whistle!

That will change though.

Going for pacemaker competition extractors. 41mm primaries and 2 1/4" flanged outlets. Perfect for twin cats. Will have a custom y pipe centralized and use VS rear section by redback as they are nice mandrel bend and straight glass packed mufflers for best flow.

Should fix your fuel economy a bit as well

[vlad01]

I reckon!, was wondering why it was a bit on and off from day to day.

lol I hear the intake is how hissing under WOT, its drawing much more air .

Have made an experimental E85 tune and 202T put in his 2c

Bought 20L to play with on the holidays.

Taking this opportunity to see if it has effects on parts and materials found in my fuel system. A jar with some stuff to soak for a long time and see what if anything happens. have 3 types of fuel hose, 24 year old genuine GM hose which I have found flawless despite the age of the hoses now, and danish made? codan brand hose. Also have metals with various different coating and platings, anodized alloy, in tank return hose (factory non re-enforced type), o ring that I use on the fuel system, viton and nitrile (N-buna?)

This stuff smells wicked!, real sweet smell and has a peanut butter after smell lol. I cant smell the petrol component though?

Finished my tank.

Also painted up some more brackets and stuff on the engine, few more to go. The1 is doing some injectors for me, ford 39lb 6 hole ones!

One of the things you need to be careful with is as it soaks up water out of the air and then corrodes metal parts that aren't coated.
Holden changed a lot of parts for the VT that went to Brazil as they run an ethanol mix. From memory steel piping needs to be coated on the inside and some rubber hoses the inside breaks down and releases little bits of rubber that can block filters and injectors.
