P0128 Coolant Thermostat DTC

Hi, TSX CU2 supercharged. We caught P0128 DTC and already done everything found on forums, including thermostat replacement. Does not matter, Second ECT sensor is enabled or disabled, we have the DTC within one or couple days. I'm not sure, but believe the problem is in ECT2 which shows ZERO no matt...

Re: DTC P1129 MAP Higher Than Expected, ITB

Sure, I personally absolutely agreed with you regarding ITB with DBW, but client does not want to give up yet )) You know, I decided just to fully close throttles mechanically when deccelerating, what will make enough vacuum and help ECU to feel happy, I hope )). And add solenoid to provide idle wit...

DTC P1129 MAP Higher Than Expected, ITB

Hi We are working with ITB setup for K24Z Accord/TSX ECU. But found we are catching DTC P1129 MAP Higher Than Expected after deccelaration with closed throttles. We run MAP-based tune with vacuum box. Yes, there are not enough vacuum, one of reason is stage 3 S2 cams, and we can not use Alfa-tune mo...

Re: Full throttle Shifting for TSX

hi, guys, do you run N/A setup with stock injectors, or ? Just have spent a lot of time to find smooth shifting on A/T CU2-turbo, but there were larger injectors, larger AFM diameter and MAP-based tune All my info is in my sig below each of my posts. Ssjoeboe is rocking bigger injectors and higher ...

A/T shifting retard and throttle

Hi

As I can see, ECU closes throttle and retard ignition when shifting on A/T. The questionn is, are there any ways, direct or indirect, to affect retard and throttle during shifts?

thanks

Re: DTC P1659 TSX 12, ETCS control relay malfunction.

For everybody who will be googling similar issue. The problem solved. It was just just fake ngk spark plugs. Nobody could not even imagine such reason affected immo, but thats it. At first immo goes BAN status during cranking cause of interferences, than ECU switches off power supply for DBW particu...

Re: DTC P1659 TSX 12, ETCS control relay malfunction.

we are still fighting with issue described above. Most probably, a reason is in immobilizer system. When first start, HDS shows status of immo - RUN, during cranking it's changing to BAN, green key starts blinking. Second start with the same way. And, finally, it does start after 3rd attempt. Always...

Re: DTC P1659 TSX 12, ETCS control relay malfunction.

Have you followed the troubleshooting steps in the factory service manual for that error code? sure, electrician checked all routines couple times. I decided to ask your advise just after another one case. The common thing is both are CU2 and run FlashPro. And we did not see such DTC on earlier mad...

Re: RDX, huge retard at 3600-4400 rpm

The ignition timing control is such crap on the RDX... I have a couple customers... 3psi of boost @ 2200 rpm and -3* of timing. I bet that drives REAL nice. Can we get some further R&D on this platform or is are inability to do any ignition timing tuning just going to be the norm? just found igniti...

Re: RDX, huge retard at 3600-4400 rpm

cut MAP and BOOST sensors and add piggyback there , clamp signals so ECU can not see more than 13 psi.
Seems, it does work, no any retard and flat torque curve.
Thanks for all who took part in my headache ))

Re: RDX, huge retard at 3600-4400 rpm

There was a problem datalogging with the RDX, including the ignition timing. Please update to latest beta version. thanks, just updated and tried. The same picture. Now I think a problem is not in software, ignition is going down fast when boost higher than 12-13 psi, no matter what numbers in boos...

Re: RDX, huge retard at 3600-4400 rpm

This behavior isn't surprising, you have limited options to tune ignition on these cars since it's apparent there is more logic in the ECU that's adjusting the timing map than just KIL. We noticed it originally when the RDX FlashPro first came out and a friend was testing it on his car. yeah, seems...

Re: RDX, huge retard at 3600-4400 rpm

Here are cal and datalog with zero limits and zero retards. Looks the same, minus 10 deg at 4000 rpm and no retards. Would like to ask guys from Hondata - is it possible that cause in updated software? When I started to work with this RDX, everything looked Ok, no such problem. You fixed MAP reading...
