    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.

    Link Extreme 1969 Mustang

    It's a 36-1 crank wheel with a hall sensor and a modified explorer cam syncronizer. It's working very well and was extremely easy to setup.
  11. I just wanted to introduce myself and my project. Thanks to Adam and a few others the progression from a Megasquirt MS3Pro that gave me nothing but problems to a Link Extreme went amazingly successful! The setup details are: 1969 Mustang Single Turbo on E85 High Compression Dart big bore block - 363"/6.0L Full sequential fuel and spark with LS coils and Fuel Injector Development 2200cc injectors. I have owned the car since the early 90's when my Great Grandfather, the original owner, sold it to me for $100. This has turned into a very fun street machine that makes nearly 1000hp and drives around as easily as it did in fully stock trim.

    Extreme fuel tables with flex and meth

    I am wondering if I can do what I am hoping or if its a pipe dream... Link Extreme running flex fuel setup on a turbocharged motor. I also have a meth injection setup spraying 2000cc/min at full throttle which is setup on a progressive duty cycle table. The issue is obviously its pig rich with full meth spray. I know i can do a switched table setup for meth/no meth but can i setup the equivalent of 4 tables? Pump gas/e85/meth/no meth? 99% of the time i will be on full e85 and I really only run the flex sensor for the "just in case I wander too far from home" and need to put in regular gas. Hasn't happened yet but it probably will some day. If i can't do the above i will just setup a full second tune for pump gas and use switching tables for meth/no meth but it would be awesome if i could do it all in one tune. BTW - I absolutely love this ECU. You guys have done a bang up job. I switched from a Megasquirt MS3Pro and this is night and day different. I am making the same power at 3 psi now as I did at 15 psi before. Nothing else on the setup has changed.

    Analog pressure sensor

    Is there a way to slow down the rate at which the Extreme registers pressure from a sensor? I have a rail mounted fuel pressure sensor and the logged pressure is all over the place but my dash mounted gauge is steady. I think it's maybe registering actual pulses from the pump and the regulator because it's displaying too fast. Can I reduce the sample rate? When I say all over the place, I mean the kpa reading is 300, 305, 289, 315, etc in consecutive log lines.

    Supported ethanol content sensors

    Must have had a bad connection somewhere. Ran new wires and boom it works great. Apparently my local station has some killer e85. Adam, off subject but is there a way to select a display unit for a particular gauge? I want kpa for everything except fuel pressure but I can't seem to figure out how to accomplish this. I have everything setup for psi on the gauge/Cal table but it still displays in kpa.

    Supported ethanol content sensors

    I have one of the small continental sensors, 13577429, and can't get my Extreme to register anything. Looking at the instructions it says it only supports 2 types, the Siemens and Continental A2C 53344228 And with either the digital input has to be setup as "GM Siemens Ethanol Sensor" which doesn't exist in the selections. Has the support changed? Do I need to swap in the VW content sensor or will mine from an Impala work fine?
