Sounds like a daft question right?

 

The problem is i'm not sure what my zed has had done to it and I'd really like to know. That way I can plan further upgrades or at least start worrying that my car's going to blow up. I think most of the work was done in Japan.

 

When it was advertised, the seller was talking about it having high 300's in terms of bhp (@ the crank) and apparently it has been rolling road tested in the past. I haven't seen any dynographs though so...

 

I know for a fact it has:

Kakimoto single exit racing exhaust

Dump Valves (god knows what make, can't see them and don't know where to look!)

HKS Turbo Timer

 

Alledgedly it also has:

ECU Chip

Boost Upgrade

Air filter upgrade

 

How can I find out what chip i've got, what boost i'm running and what air-filter i've got. I can see the filter but it might be stock as far as I know. It's not a shiny chromed thing but what does that mean - is it standard?

 

Can i find the chip somewhere and have a look? Is there someone who can test boost levels?

 

The car's in Newcastle at the moment, anyone know of somewhere I can take it for "investigation"?

 

Guesses, hypotheses and blind assumptions welcome :D

I can only help with two of your items.

Air filter - Open the bonnet and use a 10mm socket set or spanner to unbolt the panel between the lights. Once unbolted lift very slightly and pull towards the back of the car, wiggle a bit until it comes loose. Under there you will wither see a cone shaped item or a black box. If it's a cone you have induction kit. If its a black box, check my web page under engine...induction to see how to open it. If you have a paper filter then you do not have a air filter upgrade. if you have a wire mesh round the filter then you probably have K&N replacement filters (a red sticker will usually be placed in your engine bay to tell you this).

Dump Vales - These should either be viewable as soon as you open the bonnet (on the fat pipes ;) ) or you can get on the floor and look under the front bumper for things that resemble small trumpets (if you have a splash panel you may need to remove this to view them).

Chip - the chip will be inside your ECU which is located under the passenger kick plate - can't really help you identify it. Sorry

I hope this helps a little in your quest for knowledge.

do you have a seperate boost gauge fitted? do you have a boost controller (gadget in car!) or boost jets? (restrictors in pipes?)

 

what does the boost gauge read? the in car one seems to read around 12psi as standard (which is 9.5psi i think)

 

you really do need a good quality aftermarket boost gauge if your gonna mess with your boost though :)

Id also wanna see about getting a UK chip, because id guess the chip fitted in Japan has been tuned to work with their fuel which is 100RON+. If thats the case then running on our UK fuel (95ron for normal up to 98 for optimax) then you are quite likely to experience detonation which will melt your engine, not to worry you though ;)

 

Anyway, as said before you will need a decent boost gauge to get a decent reading for your boost pressure.

 

As for the chip you will have to fetch the ECU apart and there will be a big EEPROM chip most likely in a socket, this might have a name or some details printed on it.
