Please tell me what you guys think bout my map
B16a I/H/E Type r cams

 

Did another map
much cleaner imho

afr was 12.9->13.5

 

Here is some helpful information:

Edit your fuel tables in 2d mode, scale everything properly so you don't have large gaps between load rows...

Your high cam ignition timing map needs work.

 

Since its your thread I will ask you. Can I post my map here as well, or should I make another "Check my map" thread? Dont wanna be a threadjacker. BTW Read My Comments on PGMFI.

 

Sure you can post here

Where should i add and take timing?

How can i verify my innovative is working as it should?

 

How should i scale it
wont i get alot more fuel in some points

could you edit my map, so i can see how it should look

 

Your map:

Your map should look like:
-----------------

Your load columns should not be stacked in 2d mode.

 

I know what happened
My tps registers -2%
and 96% Full throttle

So i do not hit the col 10
1035MBAR


So i just adjusted the last 3 Columns together.



Would you think that is why my map looks like that

 

Yea my TPS read 3 at idle. Weird. Anyway, heres my map for your viewing pleasures.

Keep in mind its just low cam, so ignore the high cam.

Not perfect straight lines, but I like it.

14.6-15:1 at idle.

12.8-13.5 at WOT

14.6-15.5 during most of cruise

Plugs look good.

 

Why are 2 of our maps have good afr and stacked

 

Thanks for the tips
Also how should i know where to adjust timing
any pointers?

 

I like smooth transitions for timing. If you look at my map and look at the low cam timing, its a bit much for you on the low end, but overall thats what I like.

 

You must never take anyones "advice" on timing adjustment. Timing adjustment requires a dyno, and a keen eye for reading plugs. Moreso the first of those two though. This is why correctly tuning a car on the street is totally impossible.

 

Tuning WOT, Why am i making adjustments to the last 3 cols

I thought WOT tuning was the last 2 Cols
Can anyone clear this up

 

UP for help!

 

I am going to have to disagree sir. This is the 'zeitgeist' that has flooded message boards with bad info in order to pay shops for dyno fees.

Tuning timing for maximum power requires a dyno yes, but tuning timing for driveability does NOT require a dyno. On the same note, very few tuners I know of tune part throttle timing on a dyno anyway. Some do, yes, but not all and maybe not even the majority. Also, unless its a load bearing dyno, its impossible to have real world conditions simulated on a dynojet.

For WOT, yes tuning timing on a dyno is important, not necessary, but important. Running 1 degree less on the street than you would had you had a dyno isnt going to hurt a darn thing.
Plug reading is a simple and LOST art that would save hours on the dyno and make it what it was meant for, Fine Tuning and Slight Adjustments, not the entire tune.

As for WOT, yes, most people just tune the last 2 columns for WOT. I know sometimes I put the pedal to the metal and I still end up around -1" vacuum, which would put me between columns 8 and 9 in Crome, but for the most part, its the last 2.

Also, ignore people who say that columns 7 and 8 are unimportant. EVERY datalog I have ever done has touched at least portions of columns 7 and 8, so i figure if I am ever in that column, it must be important. Some say interpolate from 6-9, and thats what I did, but I still monitor it.

I recommend making some kind of a "det can" and learning how to properly use one using that, as it will help you with both part and full throttle timing

Funny thing is not one comment yet on my map. Ah well. SHoulda made my own thread/

 

Just looked @ you first map..

def. smooth out the low n high cam fuel... low cam timing could use some love as well

my .02

 

I will agree with you slightly when you have tuned cars on a dyno for power relative to timing in partial throttle areas and you KNOW what timing values are correct and generally speaking which ones will make a car run better in high rpm on/off throttle areas, then you can tune cars off of an established base timing table and not worry about it. Until then though your just assuming what ever base map your using is ok, personally I dont like assumptions.

All of this depends on how close you are to the edge of ignition advance. And that makes me sad that people think that plug reading is a "lost art", how many widebands have you used? how many have been exactly right all the time? If you are tuning a 600 hp honda for instance, what if your wideband says lambda .8 or 11.5 afr, and you look at the plug and it is totally white?

Or even better, what if you are using a stock based ECU program and that number in your ignition table isn't actually your timing advance value? How sure are you?

 

You bring up a good point here. I cant tell you have many times Ive seen people with close to stock cars post maps that are running 20-30% more fuel at than stock (which is already tuned rich) and say that there wideband says its running 13:1 and flame me when I ask them to check their plugs or test it vs a dyno. Or one guy who posted a map running stock fuel at 11psi and said his wideband read 11:1. I dont think either of these people were trying to blow up others cars, just simply using faulty widebands.

My friends make fun of me for how much I pull my plugs. The neighbors think my car is constantly broken cause I always have the hood up. Personally I have only used 1 wideband as its given me no problems.

Ah the wonderful world of datalogging. I do constantly tell people to make sure their ignition timing is at stock (usually 16* BTDC) before tuning timing via the ECU, and for the most part, all values datalogged are VERY close to what they actually are.

 

question is

since i dont log 1035mbar

should i just tune col 8 and 9?

or should i tune the last 3 columns


in for tips

 

You don't know what they actually are. Unless you are tuning on a dyno and have a fast enough eye with a timing light on the crank pulley at 8000 or more rpm you cant tell me that the plug is firing 16btdc at 20 psi (or which ever rpm and load point you want above idle)

Take a Hondata map with a car you dynoed, take ALL of the timing values from S300 and put them in AEM or Motec and see if it makes the same power. All of your corrections and final datalogged timing in OE based computers is not always correct either.

People pay good money for reliablilty. OE computers have too much mystery interms of comps you can not control.

To OP. Do not focus on tuning "2 columns" shape the WHOLE map to what your car needs. Fuel maps should always look your tq curve if you are not tuning off of a duty cycle table. You will find your fuel table will look very similar to your TORQUE curve if things are correct. Again, another reason to use a dyno.

 

Would using lower octane gas, cause me to have a richer map?
tuning for 13:1 AFR WOT

 

No.

 

did some tuning tonight

3rd gear for high rpm pulls
and 4th for low


tuned for about 13-13.5 AFR

What is weird is, if i do a 3rd gear pull, looking at freelog, data view, it shows LEAN as much as 15:1 ARF.
Buy my lc1 wideband reports 13:1 ARF

could you explain what is happening?

Also in the low cam, i have data in 1035Mbar colum
but in the high cam, i do not hit that col


Could you advise me whats going on

 

Your wideband is either wired incorrectly, or your calibration table from voltage to AFR is incorrect in your software.
