Hi all,

 

I've recently purchased a JUN eprom chip for a TT off e-bay and am awaiting delivery, does anyone have any info/specs/reviews for them.

 

Cheers

I've got a JUN 555 code. Looks OK to use on optimax. Less timing than some other tunes and fuelling not altered much.

Hi John,

 

Do the fuel/timing maps look ok to run the usual 14-15psi without too much danger of a very large expensive bang? Do you think i should expect the same sort of power gains as a JWT/SE chip or more or less?

 

Thanks

Baz

Not too sure if the one you've bought is the same as the one I have, so I wouldn't like to say. The one I have certainly is.

I can pull the maps off it for a look if you want.

U will get more power than the jwt because it's more fine tune. But if u upgrade u have to send it to jun to reprogram it
