Copied directly from the manual: "Now open the file up in Notepad and copy the first fuel map and paste it over the second one. This will give you equal maps font to rear, which is important as you are only analyzing the fuel from the rear cylinder. You will now have equal maps, but the front cylinder will automatically get more fuel." Um... I understand that we're calculating data from the rear cylinder. Everything I've read thus far states the rear cylinder needs to be richer than the front due to heat. So if I make the front cylinder a duplicate of the rear, won't it be too rich? I continued reading, and it never made mention of any further adjustments to the front cylinder map.  ~SM (Message edited by Swordsman on April 30, 2008) | ||

Carbed I4 usually had leaner main jets on the inner cylinders compared to the outers as well. | ||

You mean richer main jets on the two inner cylinders don't you?? That;s how my ZRX and Concours were.... | ||

Considering how much attention most ECMSpy questions get ("Can I reset my TPS", "Hey, how do I reset my TPS?", etc.) this one's getting skipped over. Did I stump everyone, or what? Doesn't anyone know how to use this software for anything other than the TPS?  ~SM (Message edited by Swordsman on May 01, 2008) | ||

I noticed the same thing on the tuning instructions provided by ecmspy. The rear cylinder I belive the rear should be richer than the front. You should analyze the default ecm settings and see what is done there. | ||

The ECMSPY experts don't like to discuss ECMSPY on this forum ... you may want to ask somewhere else to find all your answers. I can tell you the instructions are not 100% correct. The front cylinder runs COOLER ... therefore the intake air is COOLER and denser... therefore you need more FUEL to keep things STOICH. (Message edited by dmhines on May 02, 2008) | ||

What he said, if you look at the maps front vs rear, the front is almost always richer on the buells. | ||

Are you tuning Seat-of-the-pants, or dynotuning? | ||

If you ARE seriously considering tuning, UNLESS you have oxygen sensor on both pipes, you are only guessing. You can enrich both maps or lean both - but if you can't measure A/F separately, you can't really know how well you've done. You can't also shove the "sniffer" forward into the pipe through the tailpipe. It restricts the exhaust flow to such an extent that it changes the way the engine runs. You also can't "read" spark plugs unless you are on the dyno or track - or on a remote road where you can hit and hold a single throttle position and RPM for maybe 20 seconds, pull the clutch and immediately kill the engine, coast to the side of the road and pull the plugs. The beauty of ECMSpy is the amount of control it gives you. That is also a problem for people who WANT to make changes without access to the proper tools (dyno, racetrack, open roads) | ||

- just to be clear, I'm seriously considering it for the "resurrection" of the XB racebike... we'll see. I destroyed the race module in the crash so need to buy something and IF I can use the "stock" module with ECMSpy, I'd be good to go. | ||

I loaded "race EPROM" data on a standard '05 ECM, it did not work. (at least for me.) The bike would start but did not idle or run properly. There were many DTC faults stored too. Also the cooling fan ran continuously at high speed with the key off. I returned the ECM to standard settings and all was good again. | ||

You need to match the ecm's last 5 numbers. For your 12 the ecm you will need is gb231. Then you can load the race info on it. | ||

So if I make the front cylinder a duplicate of the rear, won't it be too rich? I continued reading, and it never made mention of any further adjustments to the front cylinder map.} The Rear cylinder with stock setting is not richer then the front. The rear is only richer in the 1900 - 3400 rpm range above 100 TPS. If you tune to the rear cylinder which has the O2 sensor and then set your front front the same + 3. you will be pretty close until you can take it into have it fine tuned. | ||

Xbswede Posted on Saturday, May 03, 2008 - Thats because they are not the same and the Eprom data locations are different. To do it you would have to manually go into each cell. Yea, I thought as much what with all the fault codes and the fan operation. Editing each cell is too much work (for me) don't need race ecm specs that bad... | ||

Thanks for the tips, swede! Hopefully I can get my data logging set up this week. ~SM |
