Hey All,

i searched and read loads of threads on ZX12r conversions from turbos to issues with clutchs and gear boxs.

How do people get them set up, can the carbs just be set up or do you need a power commander?

I dont want more power I just have a minor flat spot i would like to remove.

Thought the zx12 was injection, so throttle bodies not carbs. The original map will be set up for the standard air-box and exhaust. To maximise tune for whatever air-box/filter and exhaust you have you'll need a power commander.

I had a Dax Rush with a ZX12R (Yes I miss it )

From memory there are two basic versions, both are injected, but have different ECU,s.

Yes power commander. Although I saw some info that suggested that the early models could have the standard ECU remapped.

Mine was a 2004/5 model with a sausage filter and a Dax exhaust system.

If you do go for a power commander I may be able to find some old MAP i saved, if you have the same model engine.

As above, you will need a power commander and ideally a rolling road. It is worth it - I gained 25bhp from a remap as the standard map wont be great with your changes to the airbox and zorst. Where in the country are you?

Im in Essex around 10mins from Dax old garage, power commander it probably is then. Havent really looked under the engine at the BEC but may have a snoop at the weekend.

rf900rush - did you have a issue with exhaust noise for tracks with your zx12r?

I will get the engine code at the weekend.

My 2004 zx12 wouldn't run with the standard map in my MK Indy. It was way to rich with an ITG filter and R1 straight thru exhaust. Power commander (PCusb) and LC1 lambda in the exhaust got me tuning it the locost way, Went out for a drive recording the outputs on the laptop and then adjusting the map until it was nice at WOT (13 AFR), then set idle and lower throttle accelerations which took a lot of time, but its been running fine for the last 5 years. Should really take it to a rolling road for the amount of time it took me to get it right.

I ten yeas of owner ship never had a chance on a track day. Having Kids etc.

Noise test at the SVA test was using the same exhaust but with a RF900RR engine and loads of sound deadening material and nnly just past.
So I guess mine would of failed on many tracks.
