/r/ Fuel efficient basemaps for stock D and B engines?
what's up nigs? With gas prices soaring with no signs of change, I figured it would be a good idea to post some fuel efficient basemaps for D and B series setups..
If I still had my wideband I would make one for my stock B16A, so If you have any please provide. Thanks for your time and contribution. |
Re: /r/ Fuel efficient basemaps for stock D and B engines?
Jesus Christ it's not that hard, get a map and spend LITERALLY ONE MINUTE and you can lean the whole thing out.
But your whole question is idiotic. A basemap is a basemap, I don't make any basemaps "extra rich" in vacuum, I always make them as close to stock as possible. |
Re: /r/ Fuel efficient basemaps for stock D and B engines?
anyone who has the ability to upload a new map should have the tools to make their own. ::)
you do get one bonus point, however, for being a b-tard. and for those of you that don't know i'm referring to 4chan not the b-series :P |
Re: /r/ Fuel efficient basemaps for stock D and B engines?
hahaha.. Feel the love
but yeah, I'm tempted to lean out a p30 map but without my wideband it would be nerve racking Btw anon haets furry |
Re: /r/ Fuel efficient basemaps for stock D and B engines?
pull 10% fuel and add 6 degrees of timing ai 10-15" of vacuum
|
Re: /r/ Fuel efficient basemaps for stock D and B engines?
Look in the code and simply have the O2 sensor target a slightly leaner voltage would work as well.
|
Re: /r/ Fuel efficient basemaps for stock D and B engines?
This thread is sad.
|
Re: /r/ Fuel efficient basemaps for stock D and B engines?
JD, so when dave did my chipping, without disableing the O2 it was always trying to settle on 14.7 A/F under cruise conditions?????
Yes, I'm a tuning newb, I've got ALOT to learn........but I finally WANT to learn it. Mostly for MPG tuning. Buddy in Mich is going for 60 mpg using an updated version of my old setup and alot more aero treatments. |
Re: /r/ Fuel efficient basemaps for stock D and B engines?
Yes, it also tries to tune for 14.7 at idle.
If you bias the maps lean, while it swings rich when the O2 feedback is active, it spends most of it's time lean. Likewise, if the map is rich the O2 feedback will cause the mix to switch lean but it still spends more time rich on average. You also have to keep in mind the ECU tries to switch around .51 volts, and if the system grounds suck the O2 is putting out >.51 to get .51 at the ECU... Generally a great idea to lower the value, if you can. Also, I like using wideband closedloop on eCtune, if you have a wideband that you can program the outputs on (JAW, LM-1/LC-1, etc) then 13:1 is 0v and 17:1 is 5v and if you lose .25 volts somewhere along the way it doesn't mean a whole hell of a lot compared to the stock O2 analogy. Oh, yah? T30 for $100 shipped with no major defects is a great deal. Do it. |
Re: /r/ Fuel efficient basemaps for stock D and B engines?
well for right now I'm only gonna monitor/datalong the stock mapping until I learn more using HULOG or HONDALOG and then learn about and Ostrich or Burn1, then finally a wideband.
Slow steps, nothing major. One question I need to research is would I have a use for a knock sensor???? I've never heard my D15B7 rattle/ping under light cruising on the old Dave tune. Is there a working link to the old PGMFI Wiki? I've got the Moates Tuning with Crome v1.06 to read tonight. Mine you I'm only working on MPG right now. Heck the current motor never gets of 4000 rpm. |

Re: /r/ Fuel efficient basemaps for stock D and B engines?
Bone, here's a link to the pgmfi library, it loads a bit slow but it works
http://web.archive.org/web/200612020...ibrary/WebHome oops just noticed the guy above me posted one too |
Re: /r/ Fuel efficient basemaps for stock D and B engines?
There is no use for a Honda KS, the are only used to trim ignition at cruise for emissions purposes + the ECU promptly ignores the KS when WOT, under high load, or above 5K rpms.

Re: /r/ Fuel efficient basemaps for stock D and B engines?
JD, haven't I mention enough I'm tuning for MPG for right now.
I have reading material for tongiht :) |

Re: /r/ Fuel efficient basemaps for stock D and B engines?
What program are you gonna use? eCtune?
|
Re: /r/ Fuel efficient basemaps for stock D and B engines?
Right now, I plan on using the free Crome, then go from there. I just need to learn the basics, tuning for MPG, then decide later when I have to tune my yet to be finished D15 insane compression motor.
14:1 using stock parts. Maybe run it on E85, but around my area it's not worth it. E85 is just .10-.20 a gallon cheaper than 87. I'm thinking a .080" Cometic HG which would put the compression at about 12-12.5:1........... |
Re: /r/ Fuel efficient basemaps for stock D and B engines?
I'd bring the compression down if you can...too much ping ping if the right parts arent put together.
12 - 12.5 should be good for fuel mileage. |
Re: /r/ Fuel efficient basemaps for stock D and B engines?
E85 and 14:1 is doable, not easy.......and I would have Blundar do it.
|
Re: /r/ Fuel efficient basemaps for stock D and B engines?
If you want 12-12.5:1 on a D, go D16Y head and make sure you have plenty of quench as it sidesteps the low end pingies. PM3 flat top pistons machined to suit a Y8 head would do the number nicely.

Re: /r/ Fuel efficient basemaps for stock D and B engines?
2 Attachment(s)
JD, set back and listen :)
D15B8 with VX rods, P29's sitting .052" ABOVE deck + the DOME. Anti VTEC for a reason. Y block is even worse issue. Attachment 16213 against stock PM3 D15 setup Attachment 16214 |
Re: /r/ Fuel efficient basemaps for stock D and B engines?
ooooooh nice one, enjoy the new found torque :)

the intake ports, make em big. lots of CC's of fuel sitting in the "waiting room" ready to rush in and see the doctor as soon as the "door" opens. i thin dividers like crazy, flatten floors and enlarge injector slots to add volume without making the overall port much larger. the valvejob should be fully radiused exhaust, thin seat angle, like .040-.050 margin. intakes go 75/65/55/45/35, leave the angles sharp except just barely break the edges on the throat to 75 and 75 to 65 edge.. just a hair with a loose sandpaper strip and tranny fluid. make the seat super thin, like .030-.035.. youll get more pounds per square inch of sealing pressure by reducing the seat area. so far, all free. so you could save your money for a crower 3 and springs. only cam id spend the $$ on. thats my whole bag of tricks.. should pull 160 no problem. |
Re: /r/ Fuel efficient basemaps for stock D and B engines?
how is this for tuning for mpg
out of boost I tuned to the leanest it would go without popping misssfires and hesitation then I added 2 - 3 * of timing the end (oh, and it failed to help much lol) |
Re: /r/ Fuel efficient basemaps for stock D and B engines?
Sounds like your car has issues.
Are you logging the wideband through the ECU, or...? |
Re: /r/ Fuel efficient basemaps for stock D and B engines?
I log directly from the LC1.

Re: /r/ Fuel efficient basemaps for stock D and B engines?
15mpg on the last tank for the win. Starting from scratch with a new tune but I have to keep it on the low since I ran from the sheriff and hid in my garage yesterday. :1
Im starting to think it's the fact that 55# opening times >>>>>>>>>> 17# opening times. |
Re: /r/ Fuel efficient basemaps for stock D and B engines?
Yuriy, get your injectors cleaned and tested...

Re: /r/ Fuel efficient basemaps for stock D and B engines?
It's what the Helms says.

Re: /r/ Fuel efficient basemaps for stock D and B engines?
I'll try the injector cleaning when I get to school. My new basemap based on the M50 rather than S50 is running me at ~14-17 at light accel and 17ish at pt cruise. Stock timing with a few degrees pulled going into boost and up to 4* added in lower rpms by comparing to other tunes. My engine will soon para espanol. :8
Also found out that while I am tuned to hit straight 12 AFRs in boost, after abusing the ---- out of my MAF it now stops reading post 10 psi and up to 25psi it it goes into 9AFRs and pulls what feels like 6-10* of timing lol. Hits a wall but still pulls a little since it is 2 bar of love almost. |
Re: /r/ Fuel efficient basemaps for stock D and B engines?
15mpg? Is that normal driving or lead foot? What rpm do u spool at?
I get 30 mpg in my b16 built for boost, no turbo yet in a 96 coupe. I really want to throw the kit on but my gas mileage is much needed. |
Re: /r/ Fuel efficient basemaps for stock D and B engines?
I spool late as ---- but when I hit full boost it shoots to 9 afrs and pulls all my timing :1 so filthy rich
out of boost a i cruise around at 16-19 now with more timing mpg looks 2x as good so far i will update if i break 20mpg this tank with my latest tune :6 and normal driving vs lead food = same |

It O2 reading is disregarded as well. I'm sure that was known, but still you want to keep it in mind when tuning for economy, even though you won't be leaning ---- out above 5k. Nvm I don't know why it's relavent. |
