P08 chipping is easy... but need the parts...

You need...1. the 28pin IC socket.
2. the chip
3. Latch ic.... 20 pins
You car wat spec? I see if I have the suitable chip for you and do you have a vafc?
If you need, i can send you the items for a fee... must cover my cost mah...

Yes need to jumper J1, then the ecu will know you are use "external"vmemory- the chip.
Just use a short pcs of wire.... okay TQ

Augustine,
How many pcs you need?
Rm5/pc + rm0.50 postage + rm1.50 profit= total rm7 to your door step TQ

Bro, I have pr3 ecu with chip, need your advise
I think my chip still refer to the o2 sensor so i need a custom chip, my o2 sensor keep sending CEL & cant resolve it(even with standard ecu)
rpm cut at 8k, no speed cut
ignore o2 sensor. pls pm me the cost &
I will using VAFC as piggyback.

jombiee,

Pls understand that i do not do programming.
So you request I cannot do.

All the chip I have..feels, jun, mugen DO NOT have the o2- disable.
Normally what is disable are the knock sensors and speed limiter.
What you request can be done but that is not the correct solution cause you Fuel consumption will be bad.

What CEL do you get? CEL 1 or 41
If this is the case the correct way is you should be replacing your O2 sensor.

I have a long PR3 ecu and have chipped it, not problems....

Pls fix your o2 sensor. TQ

yeah its CEL 1, change it already, even do a bench test, voltmeter test, everything is fine, even discussed it at Hondatech, still no solution, change ecu also did not solve the problem.

anyway, so you have any chip for pr3 ? could you install the ZIF socket so that we could easily change the chip ?
ZIF Sockets

In that case, i would say it is the wires.
Need to trace it from da ecu to O2 sensor.

The p30/p08 chips seem to able to run on the PR3 that I have.
What your engine spec?

Zif socket.... no i do not use those. I just use the normal type of 28pin socket.
You need ZIF sockets only if you always change chip... do you really need those?

Where is your location? TQ

Hi there,

I am planning for the following Yokohama tyres for my 2 cars, one using 195.55.15 and another is 180.60.14

After some research online and offline, found that Advan Neova AD07 only have size for my 195.55.15 while AVS ES100 have sizes of both.

Also known that the UTQG for AD07 is 180 AA A and ES100 is 280 AA A. If I am going to take AD07 for the 15" and ES 100 for the 14", would this be my good choices?

Need your experiences on both tyres model in terms of dry, wet, treadwear...
