Wego Ii Con't
John, Yes, I have been using the WEGO II to tune my bike (2004 FXDI) with the SERT. This combination has worked really well in adjusting AFR on the cylinder with an 02 sensor (front, back or both measuring one at a time). The SERT instructions help you make adjustments w/o an AFR meter but you don't really know what's going on with air fuel mixtures w/o a meter, either on your bike or part of a dyno tune. Using a combination of SERT and AFR meter goes a long way in tuning your bike (meter doesn't help with timing adjustments). Once you get the SERT, read the manual multiple times, especially the parts on tuning w/o a dyno. Then follow the instructions, and if your have an AFR meter, you can tell if you are rich or lean at particular RPM's and throttle openings. Adjust the settings per SERT instructions (I like using the VE tables for each cylinder.)
I don't know that much about the TS 88+, but it looks like a scaled down version of the WEGO II. The SERT gives you error (trouble) codes. If you don't have an 02 sensor, the WEGO II includes that. If you don't want all the features of the WEGO II someone posted that there were still some original WEGO units available for a lower price. Bought my unit direct from DTT.
As to hooking up connections for tach, TPS and MAP, DTT told me that Tach signal is pin 3 and TPS is pin 24.(FXDI 2004) I did get the H-D Electrical Diagnostic Manual with the wiring diagrams but the problem I have had is in the practical hook up (finding pin 3, 24 and how to attach the wiring). It is very hard to get to the wiring behind the ECM and fuse box. It was a bear just to hook up a poitive wire which is ignition controlled. If anyone has had practical experience with hooking up these wires, any info or advice would be appreciated.
