    Long term fuel trim

    Thanks Adam. I have used the mixture map but it seems to only update 3-5 cells at a time. Maybe I just need to play with the settings a bit. My ve table is very close anyway so maybe I am just within the accepted limits it looks for.

    Long term fuel trim

    Is there a place in PC link to view LTFT? I have not looked at any of the statistics while the motor is running so I am sorry if that's where it is. I would like to view this to do some very fine tuning.

    Fire up problem cold start on e85

    Let it crank for a bit but not start. Key off and pull a plug. Is it wet or dry? Tune cranking fuel accordingly. Likely it will be dry and need an increase in cranking fuel.

    Bud what is the exact issue? Does it start and instantly die? Does it crank and crank but not fire? Each issue has a different fix.

    water meth injection

    I am using the devil's own tuner kit. They recommended letting my ecu controller it over their controller. I have the pump on a switch which also is connected to a digital input in my Link Extreme. When that digital input is active I use a 4d fuel/spark table to pull fuel, add timing and a duty cycle table with ssr to control a fast valve. This way the meth is always at 300 psi and the valve is pwm'd to pulse the spray. Works flawlessly. Dual 1000cc nozzles and a devil's own solenoid/fast valve.

    Dry Nitrous with 5d fueling

    I just wanted to make sure I have the right idea here. Turbocharged v8 with a large turbo which doesn't start to spool until 4300 rpm. Want to run a regressive dry n2o shot starting at 2700 rpm and tapering away to nothing by 180kpa or so. I am already spraying meth so i am using the 4d fuel and spark table to pull fuel and add timing when its active and the 5d to add fuel/reduce timing for the n2o. Will the 4d/5d tables when set to overlay be cohesive? If one is adding 2* but the other is pulling 1* it will all jive and add 1* total? Same with the fuel. Meth starts spraying around 170 kpa so there will be a small overlap. Any tips on how much fuel to add to start with? 100% duty will be 150hp shot. Not sure if there is any sort of calculation to determine how much extra fuel % to add. Its on e85 and max IDC I see is 57% at 6500 rpm and 15 psi of boost. (2100cc injectors)

    Boost cut or E-Throttle cut

    Thanks Adam, that makes perfect sense.

    Boost cut or E-Throttle cut

    So I took my car to the track today - 1/8 mile drag race. First time out with a new turbo but I did have some street time on it. 1st pass right at 6400 rpm, 1st gear it fell on its face like ignition cut then it recovered and I shifted to 2nd, at 6400 rpm again same thing so I backed off a bit to about 80% throttle and finished the pass. 7.0 at 91 mph. Looked at the pc log and I hit 235 kpa at both instances of it cutting out. I though "oh that must by my set map limit" because I usually have everything set for 15-17 psi. Dial the WD duty down a smidge and run a pass at 10 psi without issues. 6.9 @ 102 mph. Ran 3 more passes at 13 psi without issue - 6.75 at 107. I got home and looked at my map limit and its 240 kpa, not 235. Is it likely it hit early or is it more likely I had an e-throttle issue? I am using a GM LS7 gold blade TB that some have said gives issues with higher boost but I have been at 17 psi for a while now. Will the ecu store that as a code if it cut throttle due to tps vs aps disagreement? Would it have recovered that quickly? I thought it would limit the rpm until a key cycle. I may up the boost cut to 245 kpa to see if that fixes things or if it still happens at 235 kpa. I did another log without saving that first one so I don't have it to upload unfortunately. Link Extreme ecu in case that matters.

    Traction control with DBW

    I am sorry if I missed the proper settings but I am only seeing power limiting via fuel cut or ignition cut. Can you limit power via the e-throttle for traction control?

    Overdrive Control with Link Extreme

    Would this work?? Lets say I have a gear vendors overdrive unit and I want my Extreme to control it without using any of the GV electronics other than the solenoid on the unit itself. Using a single output looking at TPS/speed and a virtual output looking also at TPS/speed to determine if I am at cruise, wot or passing. Bad idea or functional? The pics show settings that allow it to shift into overdrive at a TPS of less than 50% but a speed over 40 mph/65kph but still shift into OD at WOT over 75mph/120kph. My setup is a 2 speed powerglide. I want the OD to activate at the track while in first gear right around 6500 rpm which is right at 75 mph. But I also cruise the car and want it to engage at cruise anywhere over 40 mph as long as I am less than 50%tps. I want it to downshift out of OD if i am less than 75 mph and try to pass someone on the highway. I would probably have to play with the TPS settings a bit to get it right but want to make sure this isn't a pipe dream before trying. What do you think?

    Ignition angle in logs vs table

    Crap I see that now. I picked up a new Surface tablet and somehow when setting the tune file up I guess I turned that on. It's not like that on my laptop I was using. Thank goodness for e85.

    Ignition angle in logs vs table

    So i just did a logged pull and noticed something disturbing. My timing should have been around 21* btdc but the log showed over 40*. The table had 19* plus a 4d overlay of 2* while my meth injection is spraying. Do you see any reason why this would happen? Could the overlay table cause this? Did my motor really see 40*+timing at 11psi FORD 363.pclr meth pull.llg

    fuel map maxed out

    Simon do you have stoich set for 9.x or 14.7? That makes a 30% difference in your fuel table.

    Link Extreme 1969 Mustang

    What does the trigger log/scope look like? Is the cam sync a VR pickup or Hall? Mine is a VR.

    Extreme fuel tables with flex and meth

    So the 4d correction will correct between all of the calculations? Awesome. Thanks.
