This dude is Fuking amazing guys! sent me an online tune for my barely running RB25det s1 s14.

got it dyno'd (will have graph up this week!! no BS )

the tune he sent me is a Base map. for my set up

255 fuel pump
550cc injectors
jecs adjustable fuel pressure regulator
top mount holset h1c "the big one"
greddy intake mani + q45 TB
J60 maff
stock motor.

tuned with a Apexi PFC

his base map with NO modifications earned me
350whp and 306 ft-lbs on 15psi

400whp and 366 ft-lbs on 19psi.

this was at 6500 rpm on a rb25det! i made peak power at 6500 rpm. the graph was still climbing! i just decided to let off then.
now people realize this is his BASE MAP!!
ignition timing is extremely conservative.
my AFR's where perfect. low 11's until red-line
the car drives amazing PERIOD. no issues at all.

any questions Email this dude asap!! if you need help he answers ASAP. like almost weird fast lol. even with other car questions i had too. Not just tuning related. 240sx related!
Steve. Thanks so much man! i would have been lost with out you!

Wow those numbers are respectable, Steve told me about you today. I have my appointment this Saturday. I def should make over 350, I have a lil more done lol. Night and day difference or what!! Congrats man.

there is no doubt in my mind he will..and the funny thing is i bet his BASE map he sends you will make more power and make it more reliable. dude the tune i am on right now..i bet if i could literally take it to him, he could get 20WHP more EASILY ... and 20 is probably an hugeee underestimation

Steve and I man crush each other. Thankfully the 3000 mile seperation keeps the spice up.

Great numbers. He texted me these the other day :D Great stuff! There is no reason for any 240 guy to take their car elsewhere if you've got tunable ems/standalone and need to get it running

We "SHOULD"

haha except rememeber my dyno is a dyno dynamics, which reads the lowest in the industry "heartbreaker"

Still though...last RB we had in here did 380 whp at 14 psi...cough

If you end up purchasing any of the following:

Power FC
Haltech P1000, P2000, E8, E11, E6K etc
AEM EMS
Megasquirt
Microtech

or any of the other fully reprogrammable EMS that you can tune in total real time, then yes. Either with map service or dyno time.

I am not a huge fan of the Nis-Tune because it requires you use an external emulator off-board to emulate the tune, and then you flash it into your ecu. barf.

Keep me in the loop, I am very reasonable for what you get.

Hope everyone else keeps up the tuning push. I am glad to see so many people finally taking care with their EMS. The EMS should be the first thing you invest in, not an afterthought like it used to be...

Not that he needs it, but I always vouch for Steve. One of the "OG" SR guys, and he's got as much or more invested into this community as anyone else I know.

Good chance I'll be bringing the FD down to him to play with and give that Dyno Dynamics a workout :)

lookin good sir, hella nice for a base map

congrats!

my little brother's stationed in san diego, we're making decent headway on his na-T 2j FD rx7, if he needs any tunage out in cali after we ship his car out that way i'll recommend he comes see you since big bro's cross country here in atlanta :P

keep up the good work Steve

So how does this online tune work?

You send him your specs, and then he emails you the tune?

titangts
05-17-2010, 10:09 PM
dude all i did. was emailed him my set up ( just how i told you guys on the first post!! ) just make sure what you tell him all of what you have. i even told him i have a jecs Fuel pressure reg. and 255 fuel pump. tell him everything! and what computer management you are using. for example i use the apexi Power FC. and BAM he sent me a tune. and you just plug in alllll the info he sent you into your tuning source.

just by doing this. i made 400....and thats base map. i know i've said it alot. but thats a ton of power for a online conservative base map.

awsome ! i fully trust steve shadows now with these super positive comments . steve i'll holler at you for a base map within the next month here.

it sucks only having one guy who can tune aem ems in this my whole province

steve shadows
05-18-2010, 12:05 PM
Thanks guys,

I orginally just wanted to offer the service to help people get started, but now that I have thousands of dyno tunes and EFI traning to work off of the base maps have become an end solution in itself for a lot of people new to EMS tuning

399, 350 trq whp at average 1 bar, this was on another RB25 with a really really big PT series turbo. Turbo isnt even in efficiency until around 22-25 psi though hence I'm sure he'll bring it back for more

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

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
06-05-2010, 12:13 AM
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.

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.

You are telling me that is not true?

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.

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 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.
