FlashPro Manager Beta Released

Hondata have released an update for FlashPro Manager. This update has a small change list, but the changes are big news. For more details on the new features, view this post from Hondata.

Of particular interest is the new MAP based fuel option for FN2 AFM based cals.

V1.1.9.4 changes:

  • Added grouping and right justification to the Sensor Window.
  • Added autotune function.
  • Add tool tip window to lambda and fuel overlay.
  • [Civic CTR - Euro] Added MAP based fuel table option.

FlashPro Manager Beta Released

I waited to post about this until the major issues in the release were fixed. It appears to be stable now so here's the change list - a lot of cool stuff was added to FPM in this release.

V1.1.9.0 changes:

TSX Cams, CAI, RH, Exhaust, TB, RDX Injectors

TSX cams seem to be all the rage, so here's a base cal for you guys. Complete bolt ons (listed below) with RDX injectors and TSX cams. Made 252whp/182wtq on the Church Dynapack. Tuned for sea level or near sea level (up to 1500 ft or so) driving. NOT designed for anyone at elevation. Tuned for a particular car (he knows who he is), consider it a base cal if you're not this car. If you want your car tuned, you can reach me here or on :-)

  • TSX Cams
  • RDX Injectors
  • Invidia Q300
  • Skunk2 RH
  • TSX TB
  • RRC IM

AEM CAI, Skunk2 Race Header, Full-Race 3" Exhaust

This race header and exhaust appear to be a very popular combination, so I wanted to make one of my base calibrations for it available here for all.

Honda ECM/PCM Idle Learn Procedure

Very frequently I've been asked to look at datalogs of an erractic idle. Usually the blame lies with an aftermarket throttle body or even an OEM Honda throttle body. The tell tale signs are an idle that likes to "jump" up and down or "go crazy". After the break is the procedure to calibrate the idle. I've found that I get the best results if I start the procedure with the car cold (below 100 F ECT).

In Soviet Russia Factory Wideband Tunes You

Oh aren't I just clever with that title...

But on to the point I wanted to make: we already know that the factory primary wideband (WB) oxgyen sensor (O2 sensor) is not very accurate in engine operationg conditions that require a rich air/fuel (A/F) mixture. Generally this requirement is seen on vehicles equipped with forced induction (superchargered or turbo vehicles). Fortunately, Hondata found a pattern to this nuance and has graciously provided us with the "Air/Fuel Correction" (AF.Corr) sensor value in FlashPro Manager that does a great job of correcting this discrepancy.

Unfortunately (yes, there is some bad news), the factory O2 behavior isn't limited to just this correctable discrepancy. I wanted to share some of behavior I've seen the factory O2 sensors exhibit as they fail. In the vast majority of these cases you will not even get an MIL (check engine light), and in some cases the sensor even behaves as if it is working and there is nothing to worry about. Read on for more details after the break...

Choosing a Calibration

One of the most commonly questions that I get is "What calibration should I start out with?". 

The answer to this question is actually fairly simple. Go to the Calibrations page on this site and use the filter based on your mods. Quite frequently you are not able to find a base calibration that exactly matches your mod list. No worries, the priority of mods for picking a calibration is this:

  • Forced Induction (S/C, Turbo), or Naturally Aspirated (N/A), then
  • Header, then
  • Exhaust, then
  • Intake

So if you don't find a calibration that matches your mods completely, you can go by that rule of thumb. If you have more exotic mods such as cams, superchargers, turbos and cannot find a base calibration, look into getting a professional eTune or a dyno tune from a respected K series tuner in your area. A professional tune isn't just limited to more exotic modifications. Once you've picked out your base calibration, you will want to fine tune it for your car and if you are unsure of what changes you need to make yourself, a professional tune is a great choice for your next mod.

I try to upload base calibrations for the most popular mod combinations that I see in the 8th community, but I can't cover everything as it seems to be an almost infinite array of combinations.


eDyno Updated With Several New Features

I am quite happy to say I've done a major update to the eDyno software. I want to briefly note the the major changes

  • Much more granular graph processing, with end-user adjustability in the "Datalog" pane of each uploaded datalog. You can see it labeled as "Granularity" when expanding a minimized datalog window. This will allow you to get much higher resolution in your graphs. Even the default setting of '50' (the the lower the value the higher the resolution) produces better graphs than the previous version of eDyno.
  • Experimental R18 support. This has only been tested lightly, and I won't stand by it's accuracy 100%, but it should be nice for R18 owners that want to do calibration comparisons as the relative differences are still valid. I am also more than happy to work with anyone interested to improve support. This goes for makes/models beyond the R18 as well.
  • FlashPro datalogs only: I now parse ALL sources of Air/Fuel reads out. This includes A/F, A/F.Corr and the Wideband input. You can also overlay two A/F plots (for example, AF.Corr and Wideband) to compare. There is also a feature to let you offset the second A/F reading. This feature is useful for overlaying the Wideband input accurate as we have noticed this input lags a bit behind the factory wideband read out. Again, these new features are also located in the Datalog window for each uploaded datalog.
  • Trim peak RPM is now much more accurate.

The following link is a graph that shows the difference in resolution between using a granularity of '10' vs a value of '100' (default for previous version). This is a plot comparing a customer's 30* and 40* cam angle pulls on an S/C Si:

The following link is a graph showing the A/F overlay feature. First A/F is the AF.Corr value and A/F 2 is an AEM wideband with a -50rpm offset applied to align the input accurately:


FlashPro Manager Beta Released

Some minor updates in this point release. Support added for the Brazilian Si ECU.
