E01 or T01 - Country code E is india, T is thailand

Honda ECU Part number concisit of three main components

*37820 which denotes as Honda part number & will be same
* The 3 centre characters are loosely related to model of car/engine in this case (PJT)
* The third number is not the country code but the revision of the ecu,

We should look for Middle 3 characters to identify what ECU is running, in indian Vtec case the number is same as malaysian part the only difference is the revision number when honda launched Vtec in India they detuned it,they used the same ECU but mapped according to indian fuel condition that time which was at 87octane hence the code is E01.

Per Honda rep (Mr. Somaraju from Chennai office) the ECM is not re-programmable. Though he said certain parameters could be changed. I wonder what that means. I'll find that on next Saturday from Whitefield.

true, the indian ecm's cannot be reprogrammed, just a few basic adjustments can be done.. thats about it..

also would like to add in third series the first alphabet denotes the market, t01 is usually jdm.

A, L usually USDM
J, 9, X*(T) usually JDM some UK (EDM) ecu's also listed as T
Q Australia...
you get the idea...

In the meantime does anyone has the OHC workshop/service manual or an idea how one could be procured?

Just came back from trip to WhiteField Honda. The Asst. Service Manager there confirmed that they can't make any changes to the ECM and I should learn to live with these jerks.
I do feel that the fuel quality makes a lot of difference though.
