Hondata

Customer brought in his ECU with an S300 v1 board installed for repair. Says the car has a solid cel and runs poorly. Tested the S300 in my own personal ECU which has a V1 board isntalled and working fine but with his board, D1 stays lit solid. Attempts to erase the ECU fails and I cannot upload a c...

Ok attached is a real datalog along with the calibration. Thank you for your assistance.

I apologize for not informing you of the SIM and I thought it was a valid test setting the knobs until the sensor readings in the datalog turned "green". I run a speed shop and have been repairing OBD1 ECUs for close to 10 years (since your original Hondata "staged" systems) for my clients and this ...

The ECU is on a moates engine simulator and the knobs are set into the "green" areas for the sensors. Aside from your observations which are valid for a real engine, would this affect the variance between the display end the datalog? If so, how should I set the knobs on the SIM properly aside from t...

The ignition advance cell value and datalogging table are not the same. Where are all the compensation areas affecting total timing?

Excellent - thank you. Just to validate, a V1 hardware tune will run exactly the same on V2 hardware.

If the version of Smanager stays the same, will a calibration created on V1 hardware work on v2 hardware without changes? I was asked this by a client waiting for his v2 board but in the need to tune his car today on v1 hardware and does not want to lose his investment in tuning/dyno time.

I've been installing several S300's lately and I'm spending too much time punching out the hole with a Dremel (I'm anal about how it looks). Is there anternative/shortcut/better method of preparing the ECU case?

Yes, let's show everyone how helpful you were: "I do not have the value of that part. Since the circuit board would probably need to be replaced, you would be looking at a charge of about $250" Here's is my response: You do not have the value of that part? Why did you ask for the serial number if yo...

S300-2086

Hi, I just bought a used s300 system from a friend and the surface mount capacitor at position C8 is missing/damaged. Can you tell me the value of this cap so I can replace it? Thanks!

Never mind - I found a short between pins 5 and 6 on the socket.

A customer bought a used Hondata P28 ECU with the OBD2a connector off of eBay for close to $300 dollars thinking it included the s300 - he was wrong. Since now he cannot afford an s300 board, he asked me to re-chip it - remove the s300 pins and install a socket. Since I don't have an s300 board to t...

I prepared a P28 ECU for a customer but did not do the physical installation of the s300 board. After the customer installed and tuned the car, he said everything was fine except when the car hits a bump and the ECU moves due to vibrations. I asked for the ECU with the board installed and when I rem...
