chip questions

[marchad]

when you have a chip installed is there a noticable difference
and i heard that they help your gas mileage. does anyone know how much it improves your mpg?

[kidsinister]

I don't know about improving your MPG; I would have thought that the imroved performance a chip gives would come at the price of increased consumption, but I do know the difference in performance was noticable immediately when I chipped my 318iS.

oh and by the way why is it that it is said that the chips give less hp to my 1988 325 then to the earlier years

kidsinister: did u use a viper chip?

[marchad]

i haven't used anything yet im browsing and im trying to find the right one

[brento]

i just chipped my 325i and it doesnt use any more fuel at all and i def noticed the difference... i got mine of ebay. i think they say it may save fuel because maybe with a new chip it doesnt apply to certin emision rules that it may have when the original chip was installed (thats what ive herd anyway)

[marchad]

so are you saying it won't pass smog once you put a chip in

[brento]

well im from australia
im pretty sure most chips are illegal here because of emission rules from the EPA

[marchad]

wait sorry about that i didn't know what i was saying
well thanks for all your help everyone i am looking to invest into a chip as soon i have some throw away money

[marchad]

ok so i live in california and we probably have one of the strictest emission controls if it is illegal i could always take it out before i have it smog tested

[brento]

thats exactly how i c it just take it out when u have to get it tested
thats wot ill do lol

[marchad]

ok well thanks guys for clearing up some questions i had

[black320]

Do the zone still sell a chip for the 320i cabrio, M20 engine? If so what are they like and how much?

How much are the Viper 1 and Viper 2 chips and what is the difference?

Can they be used for the M20?

Cheers
