ecu chip... (no name?)

May 10, 201510 yr

I know Noz is real good with this kinda stuff but I have a ecu chip which is soldered into the ecu with two wires... However it doesn't have a name on it and I feel this could be a cheap chip. also feeling that this could be the culprit of my bad idle (earlier called a misfire). Is it safe to test this by cutting these two wires to cut out the chip?

Thankyou

Good job you didn't go cutting any wires. They are for the archaic onboard diagnostic function.

It's a Japanese chip. I've yet to see a JDM chip that was suitable for UK fuels, but I don't think I have any Tomiyoshi files in my database. Regardless, the only way to know what's on the chip is to have it read, either via an EPROM reader or the Consult port.

Sure, no problem.

Send me the ECU and I will analyse the chip for you.

Bit difficult that aha. It's my daily drive and I am working all next week... but then have a week off. How long will I be without car?

Or I can always come to you... you are only 1.5 hour away :)

Moving on to the air conditioning.
This felt like it took me an age to get the pipe work back in, never seen such a complicated setup of pipes.
think i've managed to get them all in place however i've discovered that the aircon evaporator is bent and i cant get it to bolt back in on one side.

I'm now looking out for options to retrofit a newer aircon system.

Tyre size recommendations

I have some after market wheels on my Zed and all the tyres have perished so before it goes for its MOT at the end of the month im looking for new tyres.
The wheels are 17" and are staggered, with a 9.5j at the rear and 8j at the front.
The current tyres on the rear are 255/40/17 and a 235/40/17 on the front.

Now ive only been able to find one tyre at 235/40/17 so I want to change so I can get a decent brand, but which way do I go.
I dont want stretched look, I want a nice flat side wall look so thinking of a 245, but would this be too chunky.
The other question is if I go up a size on the front, should I also then go up on the back? Or will it not matter?
Any help would be gratefully received!

MOT time again

Last year went by very quick, my zed was also due this month, it's first MOT in my ownership.
Thankfully passed, slight oil leak as well (I have been keeping an eye on). Unfortunately some corrosion underneath too which will need sorting.
Hoping to make the trip down to Powerzed in the near future to get the car checked properly and prepped for a good year of driving and enjoying the beast.

Suggestions for Potential Valved Exhaust

Hi everyone just a quick question on valved exhausts.
I had one on my golf R and it was a game changer that allowed me to have a bit of fun when on a decent drive by myself, but reign it in when I have more reserved passengers or driving in places where I don't want to be a dick and ruin peoples day.
So was just wondering if anyone has much experience of getting these for the 1992 Z32 TT platform?
Aware there probably isn't an off the shelf option, but potentially any trusted fabricators who do good work in this area? I know Jim at PowerZed trusts the team in the unit by him to do a lot of exhaust work so they were my initial first thought, but may as well open up the question just in case there are some other great options out there too.
Long term intent as I get other work done will likely result in an aftermarket ECU so that could solve the issue of valve control, otherwise potentially a bluetooth controller would work I assume for simple open/close.
Thanks all

Adam
