memcal based L67 ecu has the proper table resolution setup for boost and the control for the s/c bypass valve later L36 flash ecu can run it but will run out of map table with the boost cranked up

Hey mate have a squizz at this currently running this modified code in my spare ecu runs better than stock, i have a few tunes to kick things off with hence im willing to give the flash ecu a go. If it doesn't work.... well i might have a wiring loom job for you or will go manual and chuck a decent aftermarket ecu in it.

Went to go get milk and bread on Saturday and it died all of 200m from my home, another bloody crank angle sensor issue for sure ecu shows no rpm when cranking mindful it could be a broken wire or something.

So to rule out the sensor im chuckin yet another new one at it, doing new o2 sensors as well so everything is fresh for when the l67 goes in. 

On scrounge for some headers if anyone knows of any???? Will be going twin 3" into single 3.5" with resonators into a Flowmaster 44 series will probably put a truck muffler at the end to knock the noise right down. Have already started hoarding parts as money allows.

Decided to go single incase i go turbo later on saves a bit of fab work and parts too. Should sound pretty mellow and flow all it puff out, after all im getting older and cant be fucked with a droning exhaust.

havnt played too far with the v6 ecus myself but that looks like it should give you  enough headroom on the maf table, could possibly use the AC pressure sensor input as a way to input a wideband 0-5v and be able to log it if you can define your own parameters and calc like im able to with HP tuners for LS

Some new parts from Rockautoparts.com and some new sensors from @vk327 

Should get things back on track, Will look into setting up a Wideband when i redo the exhaust soon so i can do some proper tuning once i get the new engine in.

Threw new O2 sensors in today runs nice and idles better took all of 10 minutes to do both fuck it was easy! Why ive not done them before now escapes me thought it'd be a bitch of a job.

Also threw in another cam sync sensor cos the one on my new engine was visibly newer for good measure.

Think ive got a theory on the crank sensor fault, may not actually be the sensor ive got 2-3 mm of float on the crank when you go to start it the starter pushes crank forward. And at low revs just the tips of the reluctor ring pass through the sensor giving a shit signal. Give the crank a nudge back and the idle improves if its pushed forward so it might just be that.

So with the ecotecs health now down graded to running but may become terminal soon, I started on stripping everything that wont be going in with the engine swap off the L67.  

Including one rather haggard in places engine loom.

Just exhaust manifolds to go and thats as far as it'll need to go.
