Hondata

OK... next question. When I road tune do I want to put it in open loop or leave it in closed loop.

I figure I should put it in open loop, road tune/datalog and adjust as needed. After all adjustments put it back in closed loop and go on my merry way.

Does that sound right?

If I get tuned, is it better to leave the ECU in OPEN LOOP or CLOSED LOOP during normal driving after the tune when I take it home? Do I want the ECU to manage my setup or do I want the maps that have been tuned to take precedence?

I'll try it this weekend and report any problems. Thanks guys for taking us seriously on the idle fluctuations.

What else does Hondata need to start reviewing the discrepancy or whatever it is because I'll data log and send anything needed? Not sure if Hondata is waiting to respond based on more input from the K-pro community?

I know that Hondata recommended that I not revert back to 1226 but I had to see if it was something wrong with the car. After a reload of 1226 and a reload of the kal... no idle problems. I then reloaded 1227 and the kal and the idle problem resurfaced. Not sure what to make of that but I hope Honda...

Here is my calibration and datalog on 1.2.2.7.

I had the same thing happen today. I updated to 1227 and when I made a few corrections to the parameters and tables my idle started acting funny. The car warms up and idles around 1100-1300 RPMs but the idle is set at 850 RPMs. If I give it some gas it increases then decreases in a wave type of patt...

How do I make it a bit richer or add more fuel to the appropriate areas? What % do I add and where to help? thanks.

I tried to eliminate the knock in my engine but instead of going down the count went up.

Two datalogs in 3rd gear and the calibation are included. Could someone take a look and see where I messed up at, also do I have belt slippage and how do I Tell.

Well I found out why I am reading -27 on short term fuel trim. In K-Pro it is my minimuma settig under the fuel tab. I think this means that my short term fuel trim is -27, so I have some major fuel triming to do. If I reduce the fuel across tables 1-8, "All Tables", do I need to follow th...

Here is the Kal I am using but it will be a day or two until I get a datalog because I have to borrow my bro's laptop. I just have a weird feeling that the fuel tables are way off.. too rich.

Still waiting!

I followed the training video to adjust my Long Term fuel trim but I still am not sure why my Short Term fuel trim is high. Right now my Long Term fuel trim reads 0 (About 15 minutes of driving). When I stop and let the car idle to check on the computer I see that my short term fuel trim is about -2...
