Upgraded Injectors Affecting Fuel Economy?

[Paulie2256]

Go into livelink and select the 'fuel' drop down. Select 'LTFT', 'STFT, and 'FUEL_PW_CLKTIC'. Pulsewidth is shown as Clock Ticks but don't worry about that and note that the value is not used the same across different ford strategies...but units aside, the logged value is very useful in reverse engineering the tuners injector scaling.!The LTFT is a simple way to see if the closed loop fuel correction is adding fuel or pulling fuel out to achieve a consistent lambda 1.0 AFR. A simple log at idle can tell you alot.

But getting back to the topic, I have found the dekas to be a quite 'economical' injector. ID1000's flow huge yet are very good on fuel also. I have found nizpro injectors to be the thirstiest of all the commonly used items out there.

Have you had a chance to check out the KPM 1000cc and 2000cc injectors? Everyone is keen on the because they are cheaper than the ID's but essentially the same thing.

Turbotrana Log the FUEL_PW_CLKTIC and I'll bet you a carton of beer your value is around 0.0009 to 0.001 indicating your low slope is less than your high.

You can get ID1000's direct from T1 Race Developments in the States for a decent price with the current exchange rate. Plus they fully characterize the injectors and have worked with SCT to provide value files for our software. They are flow matched on their deadtimes as well as their actual flow rate so they are pretty much the best you can get.
