Re: 2003 Dodge Neon (#9)
Can you sync or put some indication of crank angle and IAT control on this? Generally it looks about correct to me, there is some noise and the air pressure is bouncing around as the valves open and such. Generally you want to sample the lows for your MAP. The lows are wandering, which could be related to IAT controls, or it could be related to compression ratio's, ect.

Re: 2003 Dodge Neon (#9)
Not exactly sure what you are asking for. These pictures show one engine cycle (see the text in the corner which mentions from "0 to 720 degrees kind of"), idle valve is static and throttle pedal is not moving.kb1gtt wrote:Can you sync or put some indication of crank angle and IAT control on this?

Re: 2003 Dodge Neon (#9)
Range 62ish to 67ish. Is that ADC numbers? What is the Y units?

Re: 2003 Dodge Neon (#9)
I hope it's kPa - that's if I am using the right sensor decoding formula. I am currently assumuning that 4.5v is 100kPa and 0.5v is 0 kParussian wrote:The value stays in the 60-70kPa range, does it look right?

Re: 2003 Dodge Neon (#9)
1 ATM is 100ish KPa, so a KPa of around 62 to 67 kPa seems about correct-ish with a closed TPS. Also it's bouncing around as expected, with a bit of noise on it. Looks like most of that noise if from the sensor, perhaps some turbulence in the intake. How much does your fuel change if you assume 60kPa instead of 70kPa? What was your sensor? You might have some electrical noise that contributing to the jitter in the signal.
Do you have a vacuum gauge? If you did you could verify the pressure with a mechanical gauge. They don't cost very much.

Re: 2003 Dodge Neon (#9)
To my big surprise Speed Density has fired the engine right away. We also did a bit of driving and tuning, it simply works! The default 80% VE was not too far off, it's just a miracle.
Here are the logs:

Re: 2003 Dodge Neon (#9)
Big day for me - first rusEfi dyno run.
Stock ECU run: 121hp/127 lb-ft
1st rusEfi run ever - wooping 44hp/69 lb-ft. Right, 12 degrees advance does not work so cool
8 runs later: 123hp/128 lb-ft. More then stock ECU!
We did not tune fuel at all, the plan for the day was to get close to stock values and just test everything. Mission accomplished
full archive: https://svn.code.sf.net/p/rusefi/code/trunk/misc/logs/2003_dodge_neon/2014_dec_20_dyno/2014_dec_20_dyno.7z
This was not cheap, no idea when the next time will be - we'll see.

Re: 2003 Dodge Neon (#9)
Very nice, very nice. I'm sure you got to learn all sorts of great things. Was that SD or AlphaN? I believe it was SD. Also looks like you were consistently above stock for HP and torque. Very good for a first try.

Re: 2003 Dodge Neon (#9)
Wow, congrats! This is a great milestone.
1 hp over stock! What is up with that dip between 3k rpm and 3.75k rpm?

Good deal. I check in a few times a week hoping for new updates. Progress is progress.

Re: 2003 Dodge Neon (#9)
That's pretty cool. We'll make a tuner out of you eventually, Andrey. Maybe.
Re: 2003 Dodge Neon (#9)
Sweet. Did the Neon auto tune significantly different from how you did it on the Dyno?

Re: 2003 Dodge Neon (#9)
That "auto-tune" is still doing something weird The only progress at the moment is that it at least does SOMETHING.kb1gtt wrote:Sweet. Did the Neon auto tune significantly different from how you did it on the Dyno?
On the dyno we were tuning timing by hand while fuel was un-tuned & rich, that auto-tune is supposed to help us with tuning fuel by calculating the VE table.

Re: 2003 Dodge Neon (#9)
What I'm more impressed about than the marginal HP improvement is the bottom end gain you've gotten out of this. That's quite an impressive improvement in low end torque... I bet it's a lot more fun as well.

Re: 2003 Dodge Neon (#9)
I am pretty happy with alternator control for now, VE auto-tune seems to work - I am out of excuses not to look into acceleration handling.
Which currently sucks:

Re: 2003 Dodge Neon (#9)
Something is not right - as you see on the gauge, constant timing is expected - yet somehow at high RPM the mark not where it is at low RPM

Re: 2003 Dodge Neon (#9)
Can you capture the crank pulses and the timing pulses with the logic analyzer? It possible the timing light is loosing accuracy for a variety of reasons, or that the coil is charging and discharging differently which causes various delays, ect. What I wonder about is if the pulses are correct. Your pulses may not match the timing light results.
