Seemingly jam ecu ????

[Skimmy237]

How do I tell if this is a standard or jam ecu ??

Craig that had the car before me said it's a jam

But I thought they had stickers on them ?

Is there a way of checking the cereal number or something

[_shaun_]

it should have the sticker on it there serial numbers wont help. the seals on the side are a good sign its aftermarket

open it up and you will see the daughterboard?

[Skimmy237]

The seals are intact so that's a good sign but how do I know it's jam ? Craig said it is but I don't wanna sell it to someone if it's not

open it up and you will see the daughterboard?

Good one.

[Skimmy237]

Anyone any ideas ???

some of these ecus have a uv chip on them so if there opened it wipes the map on them, so by opening you run the risk of breaking it. short of it having a jam sticker theres noway to tell if its a jam ecu

^ this.

Dont open the seals, some of these ECUs have UV light sensitive chips that get wiped by light.

Also nobody in their right mind would buy an ECU with broken seals.

If it does all the things a P&P does, raise RPM limit, remove speed cut, raise/remove fuel cut etc. Then its gotta be a P&P no matter if its got stickers or not.

Yea I wouldn't open it don't worry, but surely there must be another way of checking it's a jam or not ? You said the seals at the side are a good sign ?

[_shaun_]

there a good sign of it being a play and play ecu but again not jam as jam seals said jam on them,

[Skimmy237]

Does anyone know what kind this is then ?

[_shaun_]

have you looked at the otherside to see if theres markings on it

[mikey4410]

close up of the tape seals ?

[Aamir]

Why not contact Craig and ask him what it really is?

[_shaun_]

looking at it again i think that it might actualy just been the sticky residue of the tamper prove seals that is left. a close up off the seal going over the join aswell to see if it is a seal or just the remains of one.

[mikey4410]

oh dear.well let us all know of any updates dude

[daniel_g]

Does it do anything that P&Ps do ?

[Skimmy237]

It doesn't hit fuel cut and it has upped the revs and all that other stuff ? It's like Chinese symbols over the seals and there's no stickers on the back

Also Craig said it's a jam

[JDMfreak]

these are called shop special ecu's the go by othe names aswell there built and modded by little tuning shops in japan there basically cheaper than jam/blitz/sard analyse and other brands from the outside they look identical to a stock ecu and some have seals and some have small stickers on them so be wary when you spot them with odd stickers there not stock ecu's

inside of a stock 4efte ep91 ecu


inside of a modded ecu as you can see the extra board that's been fitted





what your ecu might be as the sticker seals look similar size on either side

[Glanza-Ben]

As said on Facebook my bets are it's a later jam one

[Skimmy237]

Yea Ben mine looks identical to that one

[Gainzy]

Looks like Jam to me from the seals, how much value deduction would that make the ecu on market? I had to have a sticker made up for mine so when I come to sell it, I don't expect the £500 mark...

[lukEp]

It's a JAM ecu I opened it up when Craig had it he asked me to open my JAM ECU up and compared the chips and they looked identical.
