Viper 2 Chip, the first hour??

[Dan318-is]

jsut installed a viper 2 chip an iv been told it runs lumpy on idle etc for the first hour etc

can anyone elaborate on this, just for my piece of mind so i no what to expect

thanks

I don't know about an hour, but it will run a bit rough for a few minutes/miles while the ECU relearns its settings. I have the same thing on my 325 with a Viper2 chip. If the battery is disconnected for any length of time it runs quite rough for a while with the idle rising and falling, also giving it full juice in second causes it to momentarily cut out. A bit scary, but after a short while it all goes back to smoothness again.

i put mine in then disconnected battery an it ran very rough for a bit

thanks for satisfying my curiosity mate!

[Jackle]

I normally disconnect my battery first, then take the ecu out and change the chip. Saves frying anything

[Dan318-is]

maybe i shud have tried that lol

well it seems to be ok, jus gota get my throttle body back together now lol with gaskets!

[Jimbob]

The car should settle after 5 mins, max.

[Dan318-is]

i will try once iv got the throttle body properly back on no point til then

n e one got n e ideas what demlotcrew has done to his IS performance wise, iv heard a lot about it but not whats been done?

[johnono]

he has a rare 4 dr i.s, i think its from factory.
has the i.x vented discs on the back.
chip and tb i think
airbox (not sure, bmc i guess)


dunno if the cams are changed, or anything in that dept, but its got all the luxes, most put in by him,

i remember when i joined up in october, he was putting summin new on every other day

[Dan318-is]

thats the way it should be!!

cheers johnno

Demlots aint an IS from factory dude. It is a 4 door yeh, but was a M40 1.8.


And i think hes had somthing like this done, Chip, TB, taken the TB heater plate out, ported and polish inlet? or somthing,and good oil.Think there might be somthing else but dunno

[Dan318-is]

why take the heater plate out????

Can you get away with that?

[Jimbob]

It's not needed apparently, but I can't see the gains from it either tbh!

[Dan318-is]

na

i dont think il risk that one

[kidsinister]

Mate, I put a Viper2 chip in my iS and it was sorted straight from start-up, didn't need time to settle.

I don't remember disconnecting my battery either;

Must try being less of a cowboy...

Once you start the car up leave it at idle for 10mins just to give it time to settle in the chip then take it for a spin. As you done all the mods go and get it CO tested otherwise you won't get the best performance out of your car(and won't pass MOT if emissions are to high).

Demlotcrew has cams aswell, not sure what make but that's the other thing i know he's done.

Hi fellas just wondering how much you paid for your chip and would it make a difference to my 325i sport? Is it worth getting one???
