eCtune

I have pretty much the same setup. I'd a ran it out to 8K and find out what rpm will result in most power under the curve. Then shift a little bit after that for less lag. You can rev the piss out of SOHC VTEC heads with a stock cam.

Just use the existing 5V reference from the ecu and create a resistor network for the RTD sensor so that it outputs a 0-5v signal. The stock ecu has this kind of circuit for the stock temperature sensors.

See Calvin, I knew I couldn't be the only one that this has happened too. Exactly the same scenario. Hadn't used ectune in over 6 months, went to use it, license had expired, and ostrich unpaired itself. Lost a good tune. My problem for not having a backup somewhere I guess, but almost left me stran...

Actually, yes it is. Because you have to be near an internet connection for all this to work. It's good though that you partnered with Craig to work on having a piece of hardware be the license. It's just way more friendly and you don't have license the software anymore.

Went through the same shit. Haven't used ectune for 6 months. Then I start racing again and now nothing works, demon version, blah, blah, blah. Had to go through all the registration hoop-jumping again.

Whats the hardware look like for the barometer input? Does it go to one of the analog mux's? If analog, baro equipped ecus could remove the sensor and have it for another analog input, or a switch, etc. Just something to consider. Also, it looks like pin 9 on the D connector is for an external baro....

I always wanted to put an pressure sensor on the rail and let the ecu read the fuel pressure and make compensations to the injector pulse. Just a simple calculation in the code. Sounds like a a feature request; along with finding a source for a hopefully linear sensor that would need to be on a spe...

I can explain.... In the early days of eCtune (about 4 years ago) we had a few cars with variating AF's because of variating fpr's. It was my idea to remove the hose to get a stable AF and it helped perfectly! You can get your AF way more stable with the hose disconnected. You remove 1 variable in ...

Resonance will not make a fuel graph jagged. Resonance doesn't just appear. A motor will ramp up in torque to the point of resonance which will be over a few fuel cells. It will be a hump, nothing more. Are you referring to exh scavenging? Hope so. Acoustical influence on cylinder filling can do st...

Some cars you can get really smooth graphs, other cars will have weird spots where smooth doesn't work, usually do to resonances in exhuast or intake manifolds, of you you have like a tiny little turno thats spools quickly.. It really depends on the car.. Its good to always try to get a good smooth...

I'm curious when you run such a smooth graph dont your AFRs vary alot and bob up and down [but still in a safe range] as opposed to a notchy non smooth graph that has every cell tuned dead on? I'm just trying to learn here. My graphs are real notchy because I try to tune each cell so precisely to t...

i have no idea what your saying. could you post a cal or something. :wink: Look at the low cam. wow thats pretty interesting, I'm gonna give it a try tonight and see how it works. It works like a base fuel table. I would really like to see more of a base fuel table type deal or VE table, whatever y...

Look at the low cam.

What I do to tune a map is make all of the values in each column the same. Just start with the highest value for each column and make them all that number. For the most part the car will run very very smooth at this point. Just tune each whole column to get them close and then \"bend\" each column t...

Did you try messing with FV (final value)? I had my 750 RC's saturated injectors tucked away for awhile cause they sucked on Uberdata. I had to idle them at 12-13 AFR to get rid of the popping and studdering and pull a few degrees of timing at idle. With eCtune and the FV I start with a mostly stock...
