VS 5.0L Loom, ECU and Memcal Q's

[_R_J_K_]

Hey there,

Me and a mate have come across a wrecked VS 5.0L ute. He wants the engine and the transmission for his HZ, and I want all the other parts and electronic 5.0L tidbits that he can't use.

I was just wondering if the memcal and ECU are compatible for both manual and auto 5.0s like on the VN-VP V8s. Also, for a very long time I assumed that the memcal and the ECU were the same thing. Can anybody explain what they both actually do?

Also (I've already assumed that this isn't true, but I thought I'd ask anyway), are the V8 and the V6 looms the same?

Thanks.

looms are diffrent because of the extra 2 cyl's and other things
the memcal and ecu are 2 diffrent things but go together. the computer or ecu is the heart where as the memcal is the brans of the ecu. if you have a computer issue with any model vn - vt (series 1 non gen3)v8 (not confurmed as im now thinking they have a pim) and vn vr v6 have a ecu with a memcal. vt onwoods have a ram type ecu where as the vn vr have rom hence no programing is possible once its been programed (rom = read only memory, ram = random access memory)

not 100% about if you are able to use the auto memcal ecu for auto to man (i manly know newer stuff when it comes to ecu's)

VR-VS auto ecu and memcal wont work in a manual and vice versa

im lookin at converting to manual, are you saying that ill lose the ecu and memcal that are currently in my vs?

Probably should have mentioned that the wreck is a manual. I'm just asking out of curiosity because I need to know how much money I need to put in to help buy this car.

Because the running gear is going into a HZ (and will be carbied'), I'm getting the computer and possibly the injector setup.

I'm assuming there is a difference between 5.0 manual and auto looms?

Also, is there a difference between T5 and Getrag memcals/ECUs?

[VrWagz1]

Manuals= same memcal no matter getrag or T5
Ecu will stay the same, you just need to get the memcal to suit either auto or manual. You can pull the memcal out and send it to a tuner to have them converted to manual/auto and just plug it back in.

Can i ask why your mate wants to carby the motor. He could have a nice neat sweet running injected ride instead of a daggy old rough carby. Especially the VP motor with an auto or manual, it requires minimal mods to the loom to make it work in the old HZ's and just a few mods under the car to make it fit.

Yes the manual and auto looms differ slightly for the box + inhibitor switch. But manual loom = hard to find so look after it. You can mod a auto loom to suit manual, its not much effort. I think the detail are in the auto to manual conversion guide in the how to's.

This is a memcal.

Well the engine is coming out of a VS 5.0L. The car has been with his family for the last 30 years, so both him and his father know the car backwards and inside out (we're replacing the entire chassis at the moment). His car is also running straight LPG (very nicely), so for him to carby it, is almost a straight manifold swap as opposed to buying gas injectors and a new gas setup for the VS motor (if there's much of a difference). It's just something he's used to I suppose, plus he can maintain it himself much more easily.

manual looms and ecu's are rare and worth there weight in gold. will certainly go a long way to paying for a manifold to convert to carby. will also need new headers to suit different exhaust port configuration on the 304 heads

im lookin at converting to manual, are you saying that ill lose the ecu and memcal that are currently in my vs?

yes or no depending on what road you take. if you could find a manual ecu/loom then i'd swap em over and get rid of the auto stuff altogether, it's simpler. seeing as the manual ecu/looms are rare you will most likely have to modify your exsisting loom and get a memcal altered to suit the manual trans. Dr Bob (robs creative creations) is the best person to speak to

carbied 304's run well and make just as much power as efi, you might loose some fuel economy but when done right you wouldn't notice the difference in day to day driving

vt use a memcal still.
vt gen3 has a PIM.
vx v6 onwards use a flash programmed PCM.
you can rewrite an auto memcal to suit a manual conversion.

For the headers, i think theres a guy on ebay that makes conversion extractors. Here HEADERS HOLDEN HK HT HG HQ HJ HZ HX WB 5LTR EFI HEADS - eBay V8, Performance Parts, Car Parts, Accessories, Cars, Bikes, Boats. (end time 05-Jan-09 21:07:15 AEDST) But i dont know if thats a good price or not.

Thanks for the link, I'll mention that to him.
