i wonder if it would be possible to adjust the filters with the write software input into the rtek...

i'd really like to scope a knock sensor during a dyno run and look for knock and a wider field of khz.

 

What I said was "they are basically the same" in the sense the heart is a Piezoelectric device. My thinking is if the a sensor has a response characteristic close to the OEM part, the control unit should provide some level of retard. If mine is defective (no voltage output), I intend to get that cheapy (or even one like the Autozone's Bosch looking one that's in your article for $36 and just bolt it on) and experiment to see how my control unit responds to a good old smack.

 

Give it a shot. You don't have much to lose.

 

Well, here's a recent log. Temps are low. Seems to be running great, just a little lean at times, will spin the tires in 3rd at about 50mph in the rain. (you can see where the rpms shoot up=no traction)

Will start tweaking with the fuel pressure or AFM when the weather gets better, and I get some new tires and try to get it to boost 14psi safely.



The log attached is just a renamed .pdb file to .zip. O2 sensor scaling 5V=20AFR 0v=10AFR

 

what's your turbo/manifold setup?

 

S5 Hybrid To4b ?-trim

 

I'm a little late in the game..just put 2.1 in my car. How are you getting those nice colored spread sheets? Also how is it labeling your wideband? I'm using the variable resistor input for my wideband...

I'm using an N390 air flow meter(similar to S5) and am showing a max of 32.2lb/min...which my engine reaches around 5,600rpm :[

and...noticed my map sensor picked up 15.2 psi...what's the maximum it can read?

I'm using the stock timing maps(not map based) and I'd like to get a log for you guys to look at...but that means being in 3rd gear since 2nd is just wheel spin with my 245s, hard to find a nice road around here for a full tilt 3rd gear pull.

 

Guess I was wrong about the AFM...got it to register a little higher. This is a 3rd gear pull...


How do i get the wideband ratio to view properly like it does on my palm?

 

I'm no tuner, but I'd be careful with the stock timing map. 28 degrees is pretty aggressive, most I've seen don't go higher than 18 at WOT, hell, mine was locked at pretty much 6-7, but became very slow afterwards lol. Enjoy your new toy

 

The MAP sensor's maximum output is ~5V that translates to ~15 psi. Another words it's a 1 BAR sensor.

 

Why doesn't my AFM go that high!?

 

I use a 13b-re afm

 

Oh.. Rlly. Hmm... I'm going to crack mine open here soon and tweak it. If it doesn't work right I might try an s5 or 13bre one...

Under the preferences you can relabel the perameters name I believe. you need to edit the scaling for the external sensor (ie. 5v=20afr 0v=10afr)

 

I got it figured out gonna pull some timing and remove my exhaust silencer before I do more wot logging.

Are these actually AFMs or MAFs (i.e., flapless) sensors?
If they are AFMs, do they have higher CFM capacity?

 

They are AFMs. I'm not sure if their CFM rating is higher.

Decided to try a 20B AFM (NF01) and got a maximum reading of 985 from it as well.

 

20B AFM, interesting! You'd think their rating would be greater than the TIIs.

Re: the 985 reading. Is that simply a value related to the flapper's Voltage output? Then this value would be lower if the flapper for some reason is not swinging open all the way. I would phyisically swing open the flapper completely and measure the voltage output. I believe it should be Vref = 5 volts?

 

I'll do further testing.

The cosmo AFMs have a larger cross section at the opening than the S5 units so I assume they flow more cfm.

 

Anybody have any experience tuning a HBP (half bridge port) with a 2.1? Think it's at all plausible?

 

Can you switch to a s5 afm(or maf) on a s4?

 

Yep. You just need a harness side S5 afm plug.

the cosmo and S5 use the same plug.

My car is an S4.

 

Hey guys,

I was also wondering what opinions you might have for this leading timing map I have created: s5 stock ports, 93 octane.

Would be interested if you think its conservative, agressive, any advanced sections in it? especially lowed/boost i'm worried about?

Thanks!

 

I'm still a little mystified about timing. It looks ok to me, but you might want to compare them to the timing maps on page 1,2,or 3 of this thread...

 

if i switch to map based timing and plug that map into my palm. im pretty sure i am going to boost over 10 psi as i have a over boosting problem. that i hope to tune for. what is the engine going to do when it hits the wall of 0's?

 

looked back at the first page timing maps and i think i was looking at it in the wrong way. should be safe to plug in ? !
