Where does everyone start?
 
I'm fairly new to this self tuning thing using the free editors, and, I was wondering where everyone starts, like with what maps and what do you all do edit first fuel or timing, I'm just curious as everyone will have different approaches wont they ?

I start with a stock map for the engine you're tuning.. and use my shitty A/F gauge and go from there. I focus on one section at a time.. say 0-3500, 3500-5500, then 5500-rev limit. Generally, I start with fuel, then get to where I'm a tad rich, then increase timing until I knock. Then I retard. If my A/F changed (which is should a bit) I lean out until I get close to my target A/F (obviously not going to be exact due to it being street tuning).

Once you have done this, your "base map" is finished. Now it's time to hit the dyno and extract ALL your remaining power, and round out your maps witha WBO2..

If I use a stock map would it be running rich if was using 450's?

Re:Where does everyone start?
 
Depends on how you're handing MAP signal.

Some use modified ECUs with an AFC, others use ROMs written to handle positive manifold pressure.. Depends on what you feel like doing.

But yes, on a ROM that is written to positive manifold pressure, it will run rich.

However, with a ROM + AFC, it will be a fine base point.

I'm using ghettodyne (running 8 psi and 450's DOHC ZC) until i get to figure out why i cant use turboedit properly (think its my ECU PP5 soon to be PM6) cant wait to get tuning on TE 2.00 though, looks very nice ;)

Re:Where does everyone start?
 
Not to intrude on Ghettydyne's market share.. but.. uhm.. Ghettodyne is just an editor, as is TurboEDIT. The ROMs are the same.

Anything that a GhD ROM would run on, a "TurboEDIT ROM" would run on because the ROMs are both one in the same. All coded by members of PGMFI.

Re:Where does everyone start?
 
Hmm. . . . well i shall give Turboedit a blast at the weekend then when i get some free time, its just when i was using the try17 and PM7try21 bins they ran a bit crap and were throwing a few CEL's at me, the smoothest one that i have used yet was the boost rom that came with v2.3 of ghd, and it only gave me a O2 sensor CEL because my cars wiring loom doesnt support an O2 sensor

TurboEF9 01-08-2004 10:31 AM

Re:Where does everyone start?
 
That's strange because the Try* series bins are PM6 derived code, as is the GhD (GeorgeHack) bin.

Maybe something in the features of that bin is messing with your ECU in a way a more stock PM6 ROM does not... interesting..

surfer 01-08-2004 10:42 AM

Re:Where does everyone start?
 
So i'm kinda stumped, i hope i can get this sorted cos i'm busting to get to the dyno and get some figures. It cant be anything too difficult i wouldnt have thought because the PP5 isnt too much different from the PM6, just need a bit of spare time........

Re:Where does everyone start?
 
are u european? some of their cars didnt come w/ o2's (which is why the ecu is throwing the code, if it's a US pm6)

surfer 01-12-2004 06:08 PM

Re:Where does everyone start?
 
Yeah am from England, we dont have such stringent emissions control so we dont have O2 sensors on them, I've since found which pin it is so i'm going to put a direct feed of the voltage that it needs so it will read as being OK and not give the CEL, unless anyone has any better suggestions????

but how do you know the base rom wont blow up the engine... :P

Re:Where does everyone start?
 
Why would the base ROM blow up the engine? not sure what you mean . . . . ???

Re:Where does everyone start?
 
the TE2 base rom will run a car almost dangerously lean on 450cc injectors. You really need to tune it a little to avoid doing bad things. I think that's what he means, because I'm the one who fucked up the fueling settings in the first place. :)

blundar 01-14-2004 08:23 PM

Re:Where does everyone start?
 
oh yeah, the PM7_try21 might be a little bit more sane because George (who whipped it up) isn't retarded like me. :)

Re:Where does everyone start?
 
from my experiences, any sort of a/f meter is important to have and something to detect pinging. but what do i know.

Ok I see what you mean, I wasnt planning on just burning a chip with a file and then driving the ---- out of my car, I needed to get my problems sorted out with the CEL's and then get a ROM that will run in my ECU reasonably so i can start with the tuning, and was just curious as to how people go about it to get an idea of what I should and shouldnt be doing.

Thanks for the info on the TE2 ROM, what size injectors are the fuel maps scaled for? are they lean even in the vacuum maps or is it just the boost side? As far as I am aware you cannot re-scale the maps by just putting the injector size into the editor as you could on TE1.29, I'm guessing I need quite a lot of fuel as it is a DOHC ZC. I know there are a lot of questions but the more I think I am learning the more questions I seem to think of, so, sorry and thanks ;)

Re:Where does everyone start?
 
Couple things:

1. the TryXX series roms use the same size + shape tables for the NA region as a stock rom.
2. You could do far worse than to plagarize the NA JDM PM7 timing maps for the ZC.
3. The fuel maps in Dave's TryXX are intended for 450s and a B18B motor. The NA region runs 14-17 AFRs which sucks. Boost is much better... Xenocron posted a bunch of bins that are working better for him on PGMFI.
4. I wish TE2 had 2D mode, because the shape of the fuel curve at each MAP level should be almost the same between the stock PM7 and your recurved for XXXcc injector. The "spacing" between each line will be different due to the injector size difference, but the overall shape should be relatively similar. Look at some roms in Crome or UberData if you can't picture what I mean.

...on a DOHC. It runs pretty good on my SOHC. Tad on the rich side, but definately a conservative tune for a SOHC.

surfer 01-15-2004 07:55 PM

Re:Where does everyone start?
 
So let me get this straight. The boost side is setup for a B18b running 450's, so, this should run ok, if a bit rich, in my car. what about the boost timing how is that worked? It is just that the vacuum side is fucked, so if i get some stock fuel and timing maps worked on the vacuum side and reduce the fuel by about %40 should this run ok?

Oh one last Q, in TE2 when i open try21.bin the vac pressure numbers across the top look strange the first 4 are the same is this supposed to be like this?

The ROm is setup as a base tune for a boosted B18A. If you're running a SOHC, it'll work fine, a bit rch, but fine.

It is just that the vacuum side is fucked, ( I wasn't aware that the vacuum side has issues) so if i get some stock fuel and timing maps worked on the vacuum side and reduce the fuel by about %40 should this run ok?
I don't know anything about your setup. This ROM should run fine, as is, on any boosted SOHC (personally tested up to 10psi).

its for a dohc, i just got my shitty af guage and it reads halfway in to the rich side of the scale so i figure that is ok.

It is just that the vacuum side is fucked, ( I wasn't aware that the vacuum side has issues) so if i get some stock fuel and timing maps worked on the vacuum side and reduce the fuel by about %40 should this run ok?

i meant by fucked running lean and not having good timing, sorry, bad description

also my car jerks pretty bad as it hits 0 on the boost guage and the guage isnt reading any boost but when i let my foot off the throttle it dumps quite a bit out of the dump valve!!! any ideas, could it be the map sensor?

TurboEF9 01-27-2004 11:13 PM

Re:Where does everyone start?
 
I'm not sure what you're talking about. :-\

I'm not aware of any vacuum specific issues with the ROMs.

I just updated the TurboEDIT download page with the current stable ROM (now that there is one). Try to burn that and see if your car jerks the way you described before.

And we'll see if we can go from there. Also make sure you have the latest TurboEDIT editing environment installed. (*-Try6.exe)

surfer 02-15-2004 04:43 PM

Re:Where does everyone start?
 
I finally got my ---- together and finished the setup for good using a custom FMIC and s/s charge pipes so everything is good, took the car out with the stable rom and using TE try6 and it stutters like ---- but i'm sure that its just in need of a little fine tuning on my part to the ignition as it runs ghettodyne's 450.bin ok.
