If I had a dynojet I would....

I guarantee those same cars wouldnt make more than 350-360 on a load bearing dyno

souls_hb · 06-02-2010, 01:29 AM

wut up steve, damn I see you do have a big rep in the zilvia forums. And my respects to you for all the public works you do with in your community. offnote.

anybody have a power fc for sale for an s14 sr20det variable time cam??? hit me up!!!

steve shadows · 06-03-2010, 05:58 PM

whats up? who's this? haha

anyone need in person dyno tuning I am running a huge discount for June -

Going to be buying advirtising on the forum again in the next week or so also

u came to my house in maywood' u dont recognize da car on my pic. u came and did the timing for my car then did settings for my safc. told me u were the biggest anti safc person in the region.lol told me to find a used power fc on the forums.... so here i am... and i happen to stumble on this trhead, cool huh. as soon as i can find the power fc ill text u. peace out steve . stay up

steve shadows · 06-04-2010, 09:23 AM

picture is tiny

yes I do, thank you!

If you're still having issues let me know, we can work something out and I can take another look at it this weekend

5pecialist · 06-04-2010, 09:26 AM

Steve is a household name now? What's up man, this is Matt's cousin (used to have the Infiniti M35). LBC!!!

steve shadows · 06-04-2010, 09:28 AM

Cool man, how ya been!

Yes send me more business though.

sidewaysil80 · 06-04-2010, 09:50 AM

hey steve i talked with you via email a couple months ago, i didn't flake man as soon as i get back to the states i'm going through you for a djetro sr20 map. i have a STUPID question though. how do i load the map?

steve shadows · 06-04-2010, 05:50 PM

with the fc data logit interface...

or....the hand commander

ps. here are some recent pics from the dyno (where the maps get cooked)

This is assuming you haven't touched the base map though, right? Bc if you have, then there it will make things a lot harder for him, ESPECIALLY if (for some odd reason) you still are trying to use O2 feedback....

steve shadows · 06-04-2010, 11:13 PM

yeah you're not supposed to TOUCH the "base map" map portion of the d-jetro.

Its for much more detailed tuning on the dyno only.

For base map puposes you just use the inj map function to correct

Not "supposed to"...what does that mean?

I don't use O2 feedback at all, so I find that the easiest way to make changes is to enter percentage changes into the "Inj" map and then I use
Recalc Base.

This way, each time I am starting with a fresh Inj map for making percentage based changes.

Clearly, when I am done, my Inj Map reads all 1.0's everywhere, rendering O2 feedback useless, but I don't care to use that anyway, to be honest.

souls_hb · 06-05-2010, 03:13 PM

thanks steve, im goin to mess around with alternator wiring see if that the reason why the alternator is not recharging the battery. if i cant get it to work ill text u in the late afternoon see if we can arrange sumtin for sun. or tues.

02 feedback should be turned off on highly modified SRs.

Most of the 02 sensors get fried very quickly when running higher boost and more fuel anyways, making the sensors ready very wacky lambdas and crap narrow band inputs.

The "Base Map" function on the PFC is for adjusting direct voltage input to the injector. You will chase your tail forever if you try adjusting this and then also trying to adjust the same cell's inj map input because they both effect injector performance in a different way.

This is actually my biggest complaint about the PFC, especially because it confuses novice tuners with these two different maps that effectively effect the same output in a different way. All other map based units can be configured to use either VE tables or injector ms direct control, but not both simultaneously'

I don't understand.

Every resource I have ever read seems to indicate that the raw injector open time (independent of OTHER corrections) is just given by the value in the base map multiplied by the INJ setting.

So if your INJ is 1.0 and Base Map is 20.00 ms, you will get the same opening time as if it is INJ = 2.0 and Base Map = 10.00 ms.

You are telling me that is not true?

I don't adjust them both at the same time!.....I use the INJ to add/subtract fuel on a percentage basis (i.e. 10% less - 0.9 10% more = 1.1) and then use the recalc base function to map these changes in the INJ table over to the basemap, resetting the INJ back to all 1.000.....

Please explain to me if this is wrong or something....so far, it seems to work EXCELLENTLY for me.....my AFRs in the vacuum portion of my map between 2000-5000 RPM are within 2-3% of my target after datalogging.....that is pretty damn good in my opinion.

That's exactly what I said? Or at least what I was trying to get across, the Base map is the raw MS... the INJ is a correction off of that. Don't mess with the raw values unless you absolutely need to, tuning takes much longer if you go with this route

I don't adjust them both at the same time!.....I use the INJ to add/subtract fuel on a percentage basis (i.e. 10% less - 0.9 10% more = 1.1) and then use the recalc base function to map these changes in the INJ table over to the basemap, resetting the INJ back to all 1.000.....

My point is it's a lot better to leave the Base map alone and adjust the INJ map. This is my point though, there really only needs to be one map. I'm not sure why Apexi has both maps in there. Possibly because some prefer tuing off of VE and some off of INJ MS directly I guess

Please explain to me if this is wrong or something....so far, it seems to work EXCELLENTLY for me.....my AFRs in the vacuum portion of my map between 2000-5000 RPM are within 2-3% of my target after datalogging.....that is pretty damn good in my opinion.

If it works for you great. I like working off the INJ map after I set whole number values for the base map.

*Vatche* · 06-08-2010, 05:11 PM

haha steve...how many years has it been now, since i was supposed to get a pfc and have you tune it? havent got one yet. but i havent seen you in a long ass time. im back in the area so if you have time hit me up

steve shadows · 06-08-2010, 05:13 PM

Seriously. And I'm still tuning. If not for me for others.

Finally going to get my M3 project off the ground though. Doing the break upgrades next month, then suspension. Trying to get back out to Bwillow by fall

souls_hb · 06-08-2010, 05:59 PM

hey steve, i forgot to ask if u think the problem is because i have no basemap. and fuel and air mixture is not correct? and also do i need a basemap?? hit me up?

Steve, I hear ya, but I think the reason is precisely so that you can use O2 feedback in certain cells but not others....

Although, one could argue that this could be done by just having ONE map (like a base map only) and then a separate binary map (literally just 1's and 0's) to turn on/off O2 feedback in whichever cells.

Anyway, like I said, rather than copying and pasting the whole base map,

I just put my datalogged AFRs into excel and caluclate percentage adjustments (which are always of order 1), put them into the INJ, and then do Recalc Base.

It would be equally valid to just apply the percentage correction to the base map itself.

Another reason why what YOU said is better (if you wanna do it that way) is that your could in theory set up your base map to be the THEORETICAL amounts of fuel that you would need to make EVERY cell 14.7, and then use the INJ as a type of "desired AFR" correction....

You DO have a basemap....you just can't access it from the commander....

i dont have a commander i have an safcII at the moment. will try to upgrade to a power fc after i get a new wire harness.. but i initialized all settings on my safc so all i have are my basic settings( sensor check and car type).
dont know any other settings for da safc for my sr20 det....

appreciate da feedback though.

steve shadows · 06-14-2010, 05:56 PM

You have to have a reprogrammable EMS to access and control the map in real time.

You could re-write the "base" map or maps on your ECU if you have it re-flashed or "chipped" as other ECU makers offer.

Like we spoke in person, I think the PFC is the best route in the long run, but in the short run just get a new wiring harness and try using the ECU you have. it's definitely setup for the larger maf, so you have no need for the SAFC at all.

wut up steve, thank you so much for coming down and hooking me up with your knowledge. I drove my car on the freeway and no kidding it ran the best it ever has in the three years ive owned the vehicle!!! my hat's off to you! like you said the only problem i have left in the car at the moment is the stalling which is none driving under normal conditions. if i haul ass on it, a minor tap to the accelerator and its good. will do that one trick on the hose( extending it at least to a foot and a half) and will let you know how it goes... thanks for all your help steve!!

stay up.

ps, will text u when i have the harness

battle_240sx · 06-17-2010, 03:35 PM

can you do a rom tune for a rb20?? i didnt see it listed but i figured i would ask.
