Hi guys,

i really need your help, i have research a ridiculus amount to no avail...

i have chipped my p06 ecu to run a H22 motor, i added the vtec hardware and installed the socket for the chip i got from xenocron..

the p06 ecu i have is EDM and the engine is JDM. the chip is for a USDM.

when i turned on the ecu and ran the car i did get two cel lights come up.
one was the barometric sensor that is not installed in the p06 ecu so i took mine from a P13 and soldered it in. it worked and got rid of my cel for the barometric sensor!!! YAY!! but im left with a Cel light for "injectors" code 16.
this is because my ecu does not have the injector test circuitry like the USDM ecu does have. i would like to install the hardware just like i did for the barometric sensor but i do not know which transistors i need.. there are seven needed and i have plenty of ecus to hack apart for bits but none with the injector test circuit. can someone please look at there USDM ecu and tell me what transistors are used please!!! pretty please!!

the location of the circuit is in the top right of the ecus board near the silver screen writing, nr the injector driver transistors and as if looking at it with the pinout plugs on the left.. points q22, q23, dm10, q24, q25, q44, q43 are of high interest!! il try to get a pic up soon so it clarifies what im talking about, please guys help!!! cheers Rich

 

Wait. If the ECU doesn't have the circuitry, how is it looking for and throwing a code for the injector test circuit?

 

it was not disabled on the programmed chip from xenocron

the barometric sensor was also not disabled on the chip from xenocron, but i added the sensor... known as the "PA" sensor and it now does not trip the cel light..

for the injector test circuit i need;

6 x transistors "Q" numbers.... ive tried guessing these are the same as the injector driver transistors marked A143?

1 x power transister in DM10 i dont know what too use?

4 X resisters i believe are banded,orange orange red (3.3kohms) can you confirm?

4 X Capacitors i beleive are B102's can you confirm?

i am aware i could buy another chip with these two cel lights disabled and have to wait two and a half weeks for it and have to pay customs and that i could also burn my own chips with crome via buying a burner and blank chips but again waiting weeks for the bits and paying more customs charges, but i really want to add these componants to A get my car running out of limp mode and B to actually see if this can be done!

 

 

 

The above picture shows the area i need populating with componants. from all the images if searched through i cant see a side shot showing the numbers on the side of the transistors which i really need!!

Could someone take a nice close up photo of the side of these transistors pretty please

 

As close as I can get with this phone.

 

Wow i really appeciate you taking the time to photo it for me!

can you see what the letters/numbers are on the face of "DM10" transistor? and the Q22, Q23, Q24, Q25, Q44, Q43 Transistors? im assuming these "Q" transistors are probably going to all be the same

really do appeciate your help bud! Thank You

 

Not really. I'll need to get my hands on a magnifying glass. Does the colored banding on them not signify something?

 

the coloured bands are confirmed to what i have installed in my ecu at present so thats great. these are the resistors. they are 3.3kohms each with a 5% tolerance

the black square bits with three legs are transistors.

the orange componants are capacitors, I have put in "B 102" capacitors hopefully these are correct?

sorry i dont mean to teach you to suck eggs, i just want to make sure we are talking about the same componants.

I reckon adding this hardware can be done and may solve quite a lot of issues with people getting code 16 on there chipped ecus.

 

wouldnt it be better to just order the chip burner from moates.net and disable the injector test circuit?

 

i have been very tempted and to be fair i will in the not to distant future. i have lots of other ecus sitting around for breaking so i thought why not just solder in the bits.. then i can fix my problem on the cheap, not pay extorsionate customs charges and id like to make a thread as well if it does work so i can help other peops fix the same problem too..

i just need the componants numbers/letters!! there are no usdm ecus in any of the scrapyards in my area to refer too...

 

here you gomanual P06 ecu

 

i shall be getting some transistors tomorrow il keep you posted.. the capacitors shown are 100pf and the ones i had put in were 1000pf. so that probly hasnt helped..

thank you sir very much! i need to find 3x c144 transistors and 2x c114 transistors. it will be interesting to see if this will work!!

 

Just a little update...about rudy time!!!. The adding of componants did not work, so i bit the bullet and bought myself an Ostrich 2 emulator and disabled the injector circuit test via this eeprom emulator. I also added a resistor pack to correct the impedence of the fuel injectors that were on my h22 vs the old injector impedence of the 1.5lsi.... i put a base stock tune on the ostrich and it drove lovely. Then i realised a stock h22 wasnt enough so i supercharged it with an eaton m45. Got a tune shop to do the pulling of timing on my tune and it went like a bat out of hell. I cant stress enough how well the ostrich worked for me. The blower was giving me 4psi before vtec, then it dipped to 2psi on vtec.... This doesent sound alot but damn it was fast... I didnt get to my 10psi goal but it wheelspan most of the time anyway so meh. In short get yourself an ostrich 2 or an eeprom emulator and you'll never look back 👍

 

Times they are a changing there supermetzbro... have you heard of the Hondata s300 ??? Screw chips and emulators... that tech is old school.
I like it that you are a supercharger fan though.
