Why save $200? Why don't you step up and buy a Race Tuner for $500. We all spent the same price to buy our Bikes do you really believe that we can't afford to spend more than $100?

Christmas list?? Isn't that where someone else buys it for you?

 

my xieds work great!!!

 

I have 2 Dyna's and a Chev Truck, duals on the truck and a HUGE aftermarket air filter box, still have the factory 02 sensors, I did not have to take it any where to have the computer tuned/updated/adjusted or had a dyno tune, engine smoothed out, mileage increased.

If the EFI "experts" on this site can, in plain English tell me why the HD system needs expensive upgrades to function after basic intake and exhaust changes please do!!!

Please do not default to "EPA mandated", my truck operates under the same rules

 

Developing SERT is much simpler than developing the actual ECM code used by the Harley. SERT and TTS are nothing more than a human interface/computer program for passing data into parameter tables to the inside of the actual Delphi ECM code. This is two completely different computer programming disciplines.
The ECM code was developed by Delphi engineers to Harley-Davidson specifications. Developing this type of computer program is frequently called real time programming or process control programming. But no matter what you call it, it is a very distinct computer engineering discipline with a very specific skill sets required.
The programming skills required to create a SERT or TTS is essentially fairly conventional. The fact that they read and write data from a small EFI computer does not make them complex or magical. Understanding EFI is not a requirement to write this type of interface program, although it can help.
So do not assume that being able to develop SERT or TTS makes you an expert on the Harley EFI. It only makes you proficient in reading a software requirements document and developing screen oriented programs.
My comments are not intended to detract from the overall knowledge of people like Steve Cole who does have a lot of valuable information. But he should be the first ones to confirm that ECM development and interface development are completely different skill sets.

 

Missed my point completely, but of course, that is normal a lot on this forum, you own XIEDs, so of course any thing contrary is good reason to become defensive and rag on somebody. I did not mean to imply anyone could not afford to spend more than $100, quite the contrary if you took the time to read. I was assuming, since you invested so much money, you should be able to afford the tuner of your choice, so why are people scrimping on something as important as controoling the AFR on their engine? But, hey, since I am so offensive, I'll just back out and watch again, so sorry I joined in the conversation, my bad, didn't mean to interrupt.

 

So Steve,

Do you have dyno data showing XIED operation at all throttle sites versus live AFR data versus the AFR ratio Table? The question is even stock bikes from the factory with no modifications do not have calibrated VE tables. Without calibrated VE tables when the master AFR Table says 14.6 it may be a completely different value higher or lower. You add the Xied and it does like it is advertized and globally richens the AFR values across the entire RPM/TPS range. For example if the Target is 14.6 and the VE table is high it may have a real value of 14 or lower. You add the XIEd to globally richen the the bike and now you are getting real values in the low 13s or even lower. I want to make sure people do not confuse this, which works as advertized, with a professional tuned bike no matter what the tuning device. IMO there is a big difference. Calibrated VE tables or calibrated fuel values are the best way.

My XIEDs also work great, I have no complaints, also I'd like to say I had a question for Steve at NightRider, He responded very quickly and gave me the info I was looking for. In my opinion the product works great and the people at NightRider back them and are quick to answer any questions you may have.

I got your point quite clearly. Maybe you should simply of asked a question as to why we choose to only spend a hundred dollars. I answered your question in the manor in which it was written. Your above statement contains the same negative sarcasm that your first post did.

I can afford a PCIII, in fact I previously owned one. Eventually it was returned to Jamie because it had a problem that they could not isolate or fix. I have also had a Race Tuner in the past. Both I paid additional money to have them dyno tuned. The device I have on my Bike now was not because it was all I could afford. It happens to work quite nicely and I am very happy with the way my Bike runs.

Money has nothing to do with it.

 

frog 13 its not about$$$ its about a waste of$$$ when something comes along better or does the job cheaper and less intrusive into the motocycle.... why not use it. again KISS. i don't think curiser started the mud throwing. i have read pretty much of this and came away with...the feeling glens(sorry if i'm wrong),has ownership in power commander or stock in that company. i've had a pcIII on a wideglide standard down load and still did not do what this xeided has. also afuel pack on a nighttrain that was a nightmare.granted maybe the installers did not know what they were doing! but ease of xieds is AMAZING and they work 4 me

 

I, too, am familiar, to varying degrees, with both types of programming. I was not suggesting he can/can't do the real-time assembly-language or machine-code programming for the ECU. I was merely alluding to his familiarity with the inner workings.

What about using different resistive values to avoid throwing errors?
