Yeah, the size scaling steps get pretty big at these large scaling factors. For latency (and most other tables), I usually use the "=" key and type in the value that I want. ECUFlash will set it to the closest available value.

 

yeah thats ok - just get the "closest" one in terms of what the trims reveal...

I can get +- 1% on the 1050's so it should be too hard.

also I found my o-rings didn't want to seat 100% either, they are probably good enough, if I was re-doing it I would put the O-Rings in first then push the injector into them..

I ask my mech about it yesterday and he said if they were leaking I would know about it :P hehehe

 

Scaling is at 1008, but my cruise and WOT AFR is a full point lower on the WB. Will adjusting the latency upward help line the afr up to pre-install?

 

Scaling and latency changes should only be based on closed loop cruise and idle trims. Once those are dialed in close to zero, then adjust the fuel map to get WOT AFRs back to where you want it.

 

Will do. Found it odd that when I installed the injectors and rough scaled them, I still got 26mpg on 93 with the AFR at 14.7 (ish) during cruise.

 

Just thought I'd share my setup, this has worked pretty well on 2 cars now.

FIC 1050cc injectors (Fuel Injector Clinic). Mine came with a sheet showing them flowrated at 1072cc each, the second set went in an 03 and were shown at 1072, 1072, 1076, 1076.

I have been running these for a few months now with no problems other than a little sputter when 'warm starting' (i.e. car has sat for a few hours after running). As it's been getting cold here in MN, I've had zero cold-start issues and feel safe to publish these to the world.

I'll be converting to E85 in a few weeks, I'll post any updates if I make any changes.

 

I installed these injectors and used mrfred's scaling values. The car runs 100% (no starting issues or anything) and trims are good. Can't even tell they are larger than stock. Thanks mrfred!

 

You're welcome. :-)

 

I just installed my FIC1050.
Used mfred scaling and latencies on 93 pump gas (see below).
Car started after about 3 second cold after the install.
Fire up evoscan (2.1) to log trims.
All fuel trims, High, Mid, Low values started at 100%.
Let the car idle for 15-20 minutes and High fuel trims trim dropped to 85% after about 10 min but both mid and low stayed pegged at 100% all 20 min idling.

scaling = 1008
4.69-4.512
7.03-3.408
9.38-1.896
11.72-1.320
14.06-0.936
16.41-0.672
18.68-0.480

Wideband reads 14.6-14.8 bouncing.
Any advice guys, or this is normal on idle or I'm so noob I don't know what I'm doing?
Its snowing outside so I cannot log cruising yet; maybe tomorrow.

 

What version of evoscan are you running?

 

Dan - I have Evoscan version 2.1

Thanks

 

I have FIC 1050 injectors and here are my settings :

Scaling 975

Latency
4.6875 - 4.512
7.03125 - 3.408
9.375 - 1.896
11.7188 - 1.248
14.0625 - 0.840
16.4062 - 0.600
18.6768 - 0.432

 

Thanks.

I changed scaling to 975 with same latencies in my post above.
Idled the car for 15 minutes and Fuel Trim Low went down from 85% (1008 scaling) to 67%. At this rate I may have to go down on my scaling to 880-900. Voltage at idle is hovering around 14.2-14.5v.

The flow sheet that came with these FIC1050 injectors shows all four at 1192@55psi and all four at 1060@43.5psi

I will try your 14v to 18v latencies tomorrow and see what that will do.

 

I started with the latencies posted by MrFred, but then had to adjust a bit.

 

You're getting wierd fuel trim values because the fuel trim scaling in the version of EvoScan that you're using is wrong. The correct scaling formulas are:

<DataListItem DataLog="N" Color="" Display="LT Fuel Trim Low" LogReference="LTFT_Low" RequestID="0C" Eval="0.1953125*x-25" Unit="%" MetricEval="" MetricUnit="" ResponseBytes="1" GaugeMin="-13" GaugeMax="13" ChartMin="-13" ChartMax="13" ScalingFactor="1" Notes="" Priority="1" Visible="false" />
<DataListItem DataLog="N" Color="" Display="LT Fuel Trim Mid" LogReference="LTFT_Mid" RequestID="0D" Eval="0.1953125*x-25" Unit="%" MetricEval="" MetricUnit="" ResponseBytes="1" GaugeMin="-13" GaugeMax="13" ChartMin="-13" ChartMax="13" ScalingFactor="1" Notes="" Priority="1" Visible="false" />
<DataListItem DataLog="N" Color="" Display="ST Fuel Trim" LogReference="STFT" RequestID="0F" Eval="0.1953125*x-25" Unit="%" MetricEval="" MetricUnit="" ResponseBytes="1" GaugeMin="-25" GaugeMax="25" ChartMin="0" ChartMax="200" ScalingFactor="1" Notes="" Priority="1" Visible="False" />

The car has to be driven for a least 10 minutes to see any change in the long term fuel trims. At least a 1/2 hour of stop and go driving is needed to get any feel for where the trims are going.
