Memcal socket install

[greenfoam]

1. Ok Picture one is your basic memcal

2. This is the tabs you lift to remove the blue cover

3. Memcal without it's cover

4. Side view, showing v6 chips under knock board

5. Tools and socket we are going to install, remember, take a picture or write down where everything is and what direction it is facing before you pull them off

6. Use a butter knife of something like that to lift the knock board as you unsolder it's legs, don't worry the pins it's soldered too can lift up and then you push them back down with the soldering iron as it melts the solder

Part Two

7. Knock sensor is off and do the same to the eprom, starting on one end, go side to side as you gently? lift the eprom, it takes a couple of runs down from each end and then it will come off

8. Lifting the eprom

9. Eprom and knock sensor removed, socket installed

10. Everything plugged back in, just solder the legs of the socket in before you put the eprom back in the socket and solder the legs of the knock sensor back into the memcal (when you solder the knock sensor board in, try to move it as far back in it's pins original slots as you can so you have access to lift the eprom out to swap eproms, 1 extra mm helps )

[greenfoam]

Ok the whole point of putting a socket in there is so you can either, install a Atmel 29c256 flashable eprom in place of the UV light original and then you can use an adpater to plug your memcal straight into your eprom burner and reflash your program in a couple seconds, or you can just lift the eprom out and plug in a different one, the socket just makes life easier

Later on I'll make a little guide on how to make a VN performance chip in tunerpro 4, just with screenshots and stuff like that

Another thing, since if you really want to go fast the last thing you need is a knock sensor, you can just leave the knock board off and we will disable the error code in the memcal later on

Awesome guide Greenfoam, Very simple and shows exactly what you need to do. Very Nice

Cheers

Nice job there Foamie, where do you buy a socket?

hey guys/greenfoam

ive been told i have a power chip, i finnaly pulled it out too check, here is everything that is written on it, i also have a pic, can u tell me if its anything special, and if so wat it does ect?

ok so it says

on the brown base part i had written - 68767 8951
on the chip thing with a white sticker it has written - cmm668
on the blue part in a on a gold sticker as u see it says - powerchip
on the nock sensor i think its called it says - sh9311

so anyhelp guys

[greenfoam]

Well it's a custom chip of some description : ) chances are it's a early powerchip, I just say that because I don't think they would use a white sticker like that anymore to cover the eproms window. Is it anything special? probably not but might be worth a few kw's

[DavidPartay]

Thanks Greeny, you're a champ!

[VN-88]

thanks for that green, but i wish i could find out exactly if it does much... is ther eanyway off finding out wat it does, or how many killowatts it gives me, or its value,

i dont no much about memcals so im just happy mine has a better one...

but what id really like to no is if there would be a difference between my one or say a stock one re done following ur steps in tunepro... which would be better???

[HDT_aero]

vn-88 your chip could be stock you cant tell by dodgey stickers stuck on it you would have to extract the binary code from the eprom and compare it against 1 a stock code (downloadable from moates) and 2 a hsv binary (link up top) then you can compare your chip to others using the compare function from tunerpro.

Otherwise there is no way to tell if your chip has been changed or if som1 stuck a sticker on it sold and just said its this kinda chip.

in theory greenys tunerpro setup should be a better setup that what you have but like i said you would have to take your binary and compare it otherwise your only guessing.

[VN-88]

oh ok, thanks for that, i guees ill have to have a look, ive been told i need a whole new ecu en i change to manual anyway, so maybe ill check it then

[greenfoam]

The Auto and Manual's share the same ECU and Memcals on the VN, there is no difference at all, Only once you get to the VR with it's computer controlled gearbox does that change

[VN-88]

finnaly a direct answer about manual and auto ecu, so i dont have to change woohooo, that saves some money, thanks green foam

im not too sure about that actually (maybe is correct not i think about it ) but in the v8's the vp's are electronically auto shifted but the vn are still vacuum controlled ...

[HDT_aero]

vn and vp use hydrollic boxes therefore auto to manual memcals have no difference

i think your thinking vr then again im a manual owner so dont rely on my info but thats what i believe is true

[greenfoam]

Yeah the VP is the same as the VN, only the VR has the electronic shifts

[VN-88]

woohoo, that means im one part closer to my change over, or one extra part to play with or sell.. depends on how i get the parts

Top work green.
If we do make our own ECU settings, who's the good chap gonna be that burns them to the eprom chips for the fellow JC bretheran???

[greenfoam]

You'll need your own burner because it takes alot of burns to get it right

[vq~gangsta]

What about if some clueless rooking makes one with stupid settings, like advancing the timing by 50 degrees at 3 grand or something silly like that?
Can it damage the car?

[HDT_aero]

yes you can cause serious damage to you engine with incorrect settings

That's why you make many small changes untill you get what you want, that's why you get your own burner

I think i may have found a new hobby!!!

My development VN ECU grew something a while back....no more EPROM burners, realtime editing (through ALDL), 8192 ALDL and uses a standard RS-232 serial cable - and the best part is its easier if you have a VN/VP'808 ecu to start with. I will be putting together a website when i get time with the instructions on building an interface and the source code changes needed.

That's what I'm talking about!, I'll be counting the days : )
