Re: Warmup Ignition Retard

I don't think the ECU even has an error code for the idle speed being out of spec. I believe the throttle control module does most of the work. When you say 'throttle control module' are you speaking of this thing in the engine bay? http://farm3.static.flickr.com/2765/4473586655_f6f5876e9a_b.jpg If...

Re: Warmup Ignition Retard

Yeah, I understand that ECUs will adjust ignition to stabilize idle. I guess you're saying the ECU has hit rock bottom trying to bring the idle speed down. Wonder why it doesn't throw a code for 'idle speed too high' after it realized it's unable to bring the idle speed down with just ignition. And ...

Re: Warmup Ignition Retard

I'm not sure I followed what you wrote. For the 1st half, the idle speed is 1350RPM while the map calls for 1200. Then at the ~1 minute mark, the idle speed suddenly jumps to 1900 without touching the throttle and then gradually gets reduced to the idle target of 1200. So, what is causing that sudde...

Throttle vs Airflow table

I have unchecked the box for this but I'm still seeing a lot of ignition retard for the 1st minute or so. This causes a sudden increase in engine speed when it finally does get disabled near the 1 minute mark.Attaching datalogs and map. Please advise on how to fix. Thanks. Shek 70mm TP, 32.fpcal dat...

Re: 2006 honda S2000 P2101 failure

Some cars let you reflash attached modules through the OBD2 port. Can this be done with the S2000? Can we bench flash the TACM maybe through JTAG or BDM or something? Any way to put the TACM into a relearn mode? I've read about one instance of someone who was struggling with a TB related code after ...

Re: 2006 honda S2000 P2101 failure

I can look for the angle difference error table and increase the values, but this doesn't fix the root cause. No, but this will let the user adjust the set screw on the throttle plate to bring the rest angle to what is actually needed without throwing codes for the voltage being too low or too high...

Re: 2006 honda S2000 P2101 failure

From what I've noticed on my car: It seems like the S2000 ECU has a transfer function that converts TPS1 and TPS2 volts to measured TP %. The stepper motor then drives the throttle body to hit an expected TP %. If it finds the volts measured don't correspond to the expected TP %, it throws a code. I...

Re: AF Corrected value seems off

So it's been 4 years. Has a larger sample size been analyzed? Can I rely on my stock sensor if using 'AF corrected' to tune? I installed a new OEM sensor a couple thousand miles ago.

Re: WARNING: Hondata Toda map audibly knocks at high load & low RPM

I don't have a Toda header. Do you think a Toda header requires 10 to 16 degrees more timing at low RPM high load compared to a Mugen header? A 'couple' degrees I can understand but not 10+ degrees. Compare the timing maps between the two. Above 2700 RPM the timing differences seem reasonable enough...

WARNING: Hondata Toda map audibly knocks at high load & low RPM

Because the knock ignition limits low & high are set to 100 !!! This results in running about 10 to 16 degrees MORE timing than stock at high load and low RPM. This is absolutely nuts. https://lh6.googleusercontent.com/-9OeJKSTn9GY/VH4sziyNFEI/AAAAAAAAD8A/DZYFXEOiyMA/s1024/s2000%2520stock%2520vs%252...

Re: retrieve calibration from ecu

What you are asking for (storing the calibration in the ECU) is not possible. LOL, the calibration is already stored in the ECU. It is the difference in hex compared to stock. If the calibration wasn't already in the ECU what makes the ECU behave according to a tuned file even with the FlashPro dis...

Re: Analog Input? How to datalog methanol injection engagement?

You could just switch to a manual boost controller and use your current boost control solenoid driver to run a MAP vs RPM ADI map. You would need support from Hondata to do so though, so good luck with that. lol
