Thread: O/T Holden 5ltr motor chip Help

Chiptorque here in perth are masters at 5ltr holden tuning

For best results get a custom chip written by someone who knows what they are doing.

My old WB ute had a red motor with late heads and manifolds. Made 185 kw at the rear wheels with a single exhaust.

And this involves hugh $$$ .... which he is trying to avoid

His motor needed a freshen up ...as the lifters & cam chain needed replacing .... So heh ....lets chuck in a bigger cam to give it some oomph


Cost him 200 odd dollars for the .... Crane Cam "CCH286"
The oversite of this "chip install with Dyno tune" is being quoted as ... $990


I have found a seller on Ebay with a chip ... to help make a good choice ... Can anyone advise on the below

The word "Memcal" .... Is this what they call the dunnydore ECU??
The Crane Cam "CCH286" .... Is this a "mild cam" or "half cam" ??
The Crane Cam "CCH286" .... is it a "Stage 1" ... "Stage 2" ... "Stage 3" ??

Teh memcal is the style of chip used in the early ecu's. Chiptorque where the pioneers in cracking these ECU's for tuning.

I gotta wonder how you nieghbour stumbled into a cam change with out thinking about the engine managment side of things?

The memcal is the part inside the ECU which basically stores the settings for the engine. On the cover of the ECU you'll find one end which can be removed by undoing two screws, under that is a blue part clipped into the circuit board, that's the memcal. Disconnect the battery before you do!
Also once you disconnect the battery or ECU on these, when you restart bring the rev's slowly past 2,000, the rev's will drop then go back up, this is the unit "learning" the fuel/idle/etc setting.

He got the cam from a "General Auto parts store" ... They didn't know about a chip being required .... Didn't cross our mind, as he didn't think it was a dramatic change (it is obviously, now, that it is!!! )

... Figured that the motor would easily compensate for the cam via the O2 sensor

The chip can be bought in Perth .... but is worth "3 times the price" of the cam ... and then it is $$$ for +fit + Dyno

Big thanks for the above ....

Any Ideas or comment on the .... what is a "Stage 1 / 2 / 3 "


The reaction from the motor in it's current state ... is the following
The Timing is all over the place .... swings from TDC to 20 degrees // Back to TDC constantly (hunting)
The fuel injectors are on max flow (flooding)

Silly mistake, if he's that tight to do it correctly, just refit a standard grind cam

The is no shortcuts with correct tuning

Your a hard man sometimes Matt

Naa ... He's not being tight .... just looking for "options" on a unexpected 1k cost

It's just a work ute that gets him to work & back .... Just wants it to run OK .. not looking for Max output potential

Do you recon the 286 duration cam is a "stage 2"??
How's that puppy treating you?
