Working on my tune, bin inside, datalog inside, let me know what you think.
 

stock z6, 14b setup.

i was thinking about pulling it back to like 19* at the top, which is like .85* per lb. Should I go a little further since I'm still basing it out? Aim for 18* at the top or something? I'm gonna be running 10psi all said and done.

Just thought I'd get the thoughts of the more experienced first.

scroll way down for the bin and the datalog.

What do you mean by "*18 at the top or something" ?

Re: Working on new Crome basemap, recommend timing?
 

18* (*=degrees) timing at the top (higher rpm range in full boost WOT (Panty ripper))

bear with me im still a noob with this.

hey if by chance you can recommend a % of fuel increase if im hitting pretty steady 13:1 flat from about 4000rpm and up at 7psi, please do.

WHAT IVE DONE SO FAR

so far i have added about 4% fuel from 2psi to 11.2 psi on the map across the entire rpm range, and set the boost retard multiplier to .8 degrees per lb, which puts it at 19 degrees at 11.2psi, and im only shooting for a 10psi tune. am i on the right sort of track, or am i way off?

ive been reading from this http://home.mn.rr.com/keebler65/honda/tuning.html

Re: Working on new Crome basemap, recommend timing?
 

Id rock 19* up top on 10psi for a base for sure.
AIM me your CROME map nukka

Re: Working on new Crome basemap, recommend timing?
 

i usually don't pull more than .75° up top until i go over about 11psi., that's just me though :) here's how i do mine.

0-2psi = stock timing
3-4psi = -.25°
5-7psi = -.50°
8-11psi = -.75°
12-14psi= -.90°

thanks guys, im gonna test out the new map today :-*

Re: Working on new Crome basemap, recommend timing?
 

(last column vac value) + ( (0.565)*(Boost Column Heading)*(Boost %) )

This is what i use for OBD0, I dont know how well it will work for fuel values that arent in MS (millisecond) pulse widths.

Give it a shot and see if the numbers you come out with make sense. :-\

Re: Working on new Crome basemap, recommend timing?
 

dude, if you're running close to a whole point lean, 4% of fuel isn't ----. add about 12% and see where that puts you. start with big numbers to get you in the general area of where you need to be, then start adding/pulling the little ones and two's. a very generic rule of thumb is that 10% fuel is approx. 1 whole a/f point with 450's.

Re: Working on new Crome basemap, recommend timing?
 

Personally I would stay below 20 degrees at 10psi on a d-series and something around 20 on a B-series. But really to be safe, I always do 1 degree step retard on d-series and like .85 on B series. No real reason to try to make it perfect right away.

Re: Working on new Crome basemap, recommend timing?
 

NOOBIE question about the timing you are refering to...........

For example by 20 degrees timing, do you mean TOTAL tming (dizzy + ECU) or just what the ECU is adding + intial at dizzy??

ie 12 dizzy + 8 ecu = 20 total (sounds right)
or 12 dizzy + 20 ecu = 32 total (KABOOM?)

Re: Working on new Crome basemap, recommend timing?
 

yeah after i posted this i was talking to dave and he suggested that, and i increased it about 8%. Seems to be in the high 10:1 range now, cant tell for sure cause my wastegate stuck open on the way home. stupid 14b flapper. im off to ---- with it some more as soon as i take a healthy ----.

Re: Working on new Crome basemap, recommend timing?
 

Here is the map I'm working on.

So far it seems pretty decent. I had a nice datalog of it, but it didnt save for some reason, so I'll have to re-do it. (oh no ill have to drive more, hehe). Anyways it looks like I still need to add a bit more up top maybe for safety sake. It starts around 11.6:1 or so when it starts spooling and by 6K rpm or so its in the 12.3:1 range, and by redline around 12.5:1. No noticeable detonation to my ears. I been thinking of ways to incorporate a knock sensor into the user data portion of the zeitronix controller.

Re: Working on new Crome basemap, recommend timing?
 

yeah, i'd add a little more fuel and try not to go over 12:1 under boost execpt for during the initial tip in to boost. remember, power is made with timing, not .5 leaner afr ;) after you get a good solid afr, do some pulls and check your plugs, keep adding timing in small increments until you notice the slightest sign of detonation on the plugs, then back it down a little. when checking your plugs though, you have to kill the car at the top of a run and then coast to a stop.

Re: Working on new Crome basemap, recommend timing?
 

yeah i am contemplating geting back in the car and doing another couple pulls to get some datalog to come home and play with. stupid file didn't save right on the last one. grrr...


ok so i went back out. i cant tell if i am hearing detonation or just the dumptube...but the AFR's are safe.

let me know what you think.

here is the bin I am running, its changed since two posts ago when i posted the link

not bad, your inboost fueling is almost right on. Just need to start tapering the fuel out after 6.5ish as the TQ begins to dump.
Hit me on AIM. I changed a few other little things.

Re: Working on my tune, bin inside, datalog inside, let me know what you think.
 

will do. i hadnt done any fine tuning yet, this was just increment increasing the fuel by % in big blocks until #'s were close to where they needed to be.

Re: Working on my tune, bin inside, datalog inside, let me know what you think.
 

dave raped my map so im gonna try out his version now. he did kinda what i hadn't gotten to yet, which was smoothing ---- out and cleaning up the mess, so i guess i can just move right to fine tuning.

Re: Working on my tune, bin inside, datalog inside, let me know what you think.
 

It looks like you have a good tune going from that log...

Quite a bit richer than I am though, I think I might add some more fuel to my maps once I get my car back together.

Just a question. On keebler's page where he talks about tuning he shows what he calls "the golden rule", it says that under boost the AF ratio should target 12.1:1. So that's what I targeted for my tune...

What are the benefits of tuning richer than 12.1:1 while in boost like you did?

Just for reference... here's the last tune I had on my car... I converted the log into excell though and expanded the AF scale so you can really see all of the imperfections...(I'm not trying to hijack your thread, just learn as much as possible)

Re: Working on my tune, bin inside, datalog inside, let me know what you think.
 

i still need to lean mine out a bit... im hitting into 11.3 and 11.4:1 in spots, i want to be more like 11.8:1. Running slightly richer like that is nothing more than peace of mind for my ringlands.

too bad its so wet, i want to check out your car. no PIR tonite.

Re: Working on my tune, bin inside, datalog inside, let me know what you think.
 

Yeah, I am going to be working on the head gasket tonight and tomorrow...

I need to figure out how to do a step retard for my map... it feels a lot slower since I changed the retard from .75 to 1... I mean, a LOT slower...

Re: Working on my tune, bin inside, datalog inside, let me know what you think.
 

Found out how to do the step retard ;D

Just in case you haven't read this yet... it explains exactly how to set it up in UD...

I'm going to do this to my maps and we'll see if she feels any less sluggish going into boost!

Re: Working on my tune, bin inside, datalog inside, let me know what you think.
 

yeah 1 deg per psi is way too much.

Re: Working on my tune, bin inside, datalog inside, let me know what you think.
 

does anybody know if there is a step retard plugin for crome?
