Your "big chip" might be an NVRAM to allow live tuning over OBD not something I've used but if you swap out for a stock ecu your mace chip will drop in.

Or get someone on pcmhacking.net to send you the .BIN file and flash it onto the existing ecu yourself.

Id need to find someone to help load it, ive been on pcm hacking and all the lingo and ecu programming just confuse me lol,

This chip is on a vs long type holder as opposed to a vt short type (as used in roller cams), i had the original chip made to delete factory security and run my vk setup, but now have a cam so need to find one to suit. 

I cannot swap it out for a stock vt ecu as its a vt roller block with a vs ute ecu that runs on MAP/multi point injection as opposed to vt MAF/AFM/seq injection/knock sensed/different wiring.

Ultimately the solution would be to run a roller cam tune in vs memcal like the one ive got.. but mace is a bit slow in replying if thats possible.

beware of the mace memcal they  are spotty  at best for actually  being tuned, definitely  throw a wideband o2 at it and check fueling is safe, going off prior experience will have bugger all timing in it as well

Do you know any other options for memcals ? 

Anywho doing more sanding, welded up a bunch of small holes to prevent moisture seeping in behind filler, some rough filling, will mostly get sanded out . 

Apparently my vs v8 memcals different to the factory roller v8 one so they cant provide one? 

More sanding 

and rust converted surface 

While im here

Still waiting on mace Australia so send me the right memcal... ive got everything else to put it together, gaskets etc.

some say you can block the cam chain oiler off as its not needed, ive restricted it but it will still oil a little bit, my theory is its there for a reason, but this may help with oil pressure the block slightly more? out with the old

Good to know, itll get it driving at least, tuning and electronics is not my strong point so yea definitely will have to look at a wideband to monitor it, when funds allow. .

@Vk304, I did not know Mace made a roller cam for the Iron Lion? When I was researching for mine, all of their 304 stuff was for flat tappet cams.

Yea its their next generation products i guess, i believe its a crow cam just rebranded? I brought it as it was cheapish and had all the parts, they sent me the wrong memcal tho so gotta wait for that now haha. Probably not a massive power increase but should sound mint ay

VL v8 lsd disc brake diff, will be getting upgraded to  trutrac center soon and 31 spline axles to  handle future plans for big power (might shorten it 30mm each side as well), will also be getting  a macdonald bros 4 link and viking coilover setup. currently has 3.23:1 gears, thinking about dropping in the 3.45s i have, give it a bit more off the line

Awesome man, i was thinking of getting one of them true trac style/mace torque lock 28 spline centers for mine. Whats your power goal?

What diff you running in this? 

When i say i took a lot out i mean a lot haha... not in the head but intake probably 10mm out of the bend, a little too much here woops, its covered and not visible though so no worries really.

Just wrote a whole story and hit 'c' on accident grr, anyways i started today on the intake and slight head porting/matching/opening up passages, only very slightly smoothed out the passage in the head.Took a lot out of the bend areas so it has a straighter shot at the valves, also opened up the intake plenum ports a lot as they narrow up just before the head and are significantly smaller than head ports...Cleaned up hydraulic roller lifters,  soaked in petrol for several hours, they seem in good condition so dont feel the need to replace.

Comparison of holden 5l hydraulic lifters vs hydraulic roller lifters-Cleaned out by removing retaining clip, blowing compressed air into lifter untill bore pops out, can take a bit of back and forth...Bit of gunk in them, cleaned out and put fresh oil in them before re-assmbly to have them pump up as soon as engine starts again, also blew out roller needle bearings and put fresh oil on them..Kept them in order to have them go back in their respective bores, this is is just maintenance and checking for wear really, but she passed qc and now onto the cam chain and cam ...

Passenger springs, hardened locks installed without a hitch, all pushrods look straight and true, no funny signs of wear on the valvetrain and none of the valves leaked air through the intake when i was installing springs which is good

Intake off to remove hydraulic lifters which ill give a clean when i research on what the best method is, and gaskets will now be added on things to buy .....

Probably do a little porting on the intake and throttle body areas now its out too...

Made a little valve spring compressor thing to compress them out of some 5mm steel, have managed to do one bank today, definitely more pressure on the valves now, used air to hold valves up while swapping them out, tedious but not a hard job. . . 

All the parts now the work...

Well after a bit of troubles at home ive picked myself up and started stripping the engine bay for a paint, and got a cam, just buying the cam chain set soon and ill teach myself to dial it in. Cant bring myself to pull the whole motor so may be a slightly awkward paint job but we will see 

Made some little panels to bring lip closer to door profile, will need to make final versions, and weld them on when i have time...

They also hide the welded mounting nuts that attach the bumper and one of the welds that joined the extension i made to the hilux lip to fit the van, less sanding when i go to paint the thing satin 

Lowered front.

I think it looks better.

Cut up a hilux lower lip had to take 150mm out of it.

Could even add a mild splitter to it... should it be black, or white like body, im not sure ... maybe let me know?
