For the last week or so when I start my car up my check engine light comes on. After driving it for a while it goes away. While the light is on I accelerate and make the transition from vac. to boost, hondata cuts the boost off. However once the light goes away, I am boosting fine. I have had hondata for several months now and it has just started acting up. I try to jump the test plug to read the cel but I get no flashes from the light. It does not light up every time. It is happening more than before though. Anyone got a ideas?

FYI also. When I go to get my car tuned and the hondata is hooked up the cel light will not go off initially to be able to tune the car when the laptop is hooked up. When I switch to another chipped ecu it will work. So my tuner uses his ecu and then switches it back and my car runs fine.

 

Sounds like a bad soldering connection somewhere.

 

Thats what I would have thought but when a CEL light comes on you have to actually reset the ecu to make it go away right? This light will go away own its own with some driving. Happened to me this morning. And I also still don't get why my ecu won't hook up to the laptop and not throw a cell to tune but another ecu works fine. However when I plug in my ecu with the new chip it works fine as far as the car running. I'm confused.

 

Uppers we go....

 

that is hondata for you.

 

Yeah well the hondata save my motor the day my wastegate line come off and i was in "superman boost". Hondata shut her down.

 

Id put money on your eeprom socket/connection not being up to par.
Unplug your eeprom and gently bends the legs out. The idea is that when you resocket it, the legs of the eeprom will be applying pressure to the cheap dual '***' wipe socket.
Ofcourse be gentle with the pins. Try to uniformly bend them. ie. not with your fingers but with a straight edge or the corner of somthing.

Please post up your results.

 

cool man thanx for the info I will try that as soon as I get off work. That sounds reasonable cause it didn't start doing this till I put another chip in.

Got home and tested your idea and it worked. I bent out the legs of the chip again a shelf and made it to where the legs were pressing out on the socket and no more CEL. Thanks a lot man. You saved me a big headache.
