Anyhow, this issue is of particular importance to me because my engine has less than .015" of v2p at 50deg advance. Technically, things should not touch, but the knock count goes crazy when the cam advances to 50deg, so I limit the cam angle to 40deg via the ECU. This is with no advance/retard...

With non stock cams to determine the actual position of the cams you need to use a degree wheel on the sensor end - not easy to do. You're hitting the pistons with the valves. 0.015" is far too little - there is 0.030" stretch in the rod at high rpm, and the piston can rock around too. Ye...

If you retarded the exhaust cam 20 crank degrees then the ECU would generate a cam phase error. If the error was disabled (which, by the way, is something which should never be done) then the ECU would probably run the cam positions from an error recovery table - I'm not sure of what offset the int...

VTC works by comparing the intake to exhaust cam sensors. eg 25 degrees intake cam advance means that the ECU will move the intake cam until the intake cam sensor shows it is 25 degrees ahead of the exhaust cam. If the exhaust is rotated, then the ECU will adjust the intake cam by the same amount, ...

Ignition and fuel timing is determined from the crank sensor. The intake VTC angle is relative to the exhaust cam. Changing the exhaust cam will change the intake cam by the same amount. Looking your other post to do with cam phase errors, what problem are you seeing? Can you clarify the statement ...

I was going to ask for user defineable RPM and MAP break points, but I just realized that you can already do that by right clicking on the value in the column/row header. sweet. Stock breakpoints worked fine for stock redline. Now that I'm revving higher, re-scaling the upper part of the map is key.

It is a minimum of $100 plus shipping to swap a good K-Pro board to a new ecu. We then keep the damaged ecu to ensure that it does not re-enter the market. Thanks for the reply. It seems likely that the cost of a used ECU + mainboard swap would be the ideal. What is the RMA procedure if any? Is the...

ECU hardware issues

I'll tell the story from the start so you have all the details in chronological order. A customer/friend of mine has a 2005 Civic SI. He installed a used Greddy turbo kit on the car shortly after purchasing it. Unfortunately, the used kit did not have any heat wrap provided. The net result is that h...

The daughterboard communication error is caused by very low battery voltage while starting the car. It is caused by: - using a smaller capacity battery than stock - relocating the battery - using a battery which has been damaged by a deep discharge - engine swaps with incorrect wiring thanks for th...

Typically the cause is the KPro board coming loose, the soldering of the pins into the ECU or the soldering of the two jumper wires on the bottom of the ECU. Sometimes these problems do not occur immediately until either vibration or colder temperatures results in an intermittent connection. I've j...

everything looks okay, your k count is 349?!?

I see only one lean spike in there. Doesn't look like the lean cut was engaged there though.

Try to change the lean cut so that it only engages at high engine loads.

where's the datalog?

definitely sounds like you're hitting the lean cut.

The A2 and A3 knock sensors have different part numbers. They will produce a similar output (electrically), so can be swapped. We have not tested the sensors to see if they produce different readings. Awesome. I have a spare k20a2 and k20a3 knock sensor lying around. Maybe i'll conduct an experimen...
