Damn sorry for the suggestion. I only suggest cuz I guess I like to help everyone out and get more people working on these type of project. Even though ceddy is here and he's the frontman over there

Also, if you email a mod over there, tell em you have a lot of EVO ECU experience and tell them your EVom name, you can get cleared to go into the tech sections.

 

Sorry, that wasn't a dig at you, more at their laziness to deal with newbies which keeps knowledgable people away who don't feel like posting 50 posts in the rookie sections.

 

The 50 post rule is probably the main reason new members do a bunch of pointless useless posts that are just annoying.

 

Yeah I can argue their rules all day but I dont want to bash them or stray so I will refrain since its not the members I hate, just the site rules.

 

Is the Maf Adder a hex or decimal value? We now have 40 thrown in as another possible MAF adder for the 2g?!? Great.

I'm running the MAF scaling that is basicaly the 2g values -76 and that has me at good fuel trims.

 

The maf adder value is displayed in decimal.

 

hows this coming jamie, get all the bugs worked out?

 

Still looking for a TPS for a 91-94 Eclipse with connector so i can install my new throttlebody. Until then, trying to dial-in anything is hopeless since the TB on the car is beyond shot. PM me if you know anyone with one.

 

Ok. That's what I've been thinking. I don't have my computer near me since I'm traveling this weekend, so I couldn't look it up in ecuflash. Since I made that last post, I've done some digging around.

------------------------------------------------------------------------------

In regards to the link posted saying the 2g MAF size is 40...

From: http://www.hwnd.org/#maf%20compensation
First of all, this calls the adder a multiplier. We'll overlook that.

Maybe the 1g has a decimal MAF adder of 100 and the 2g has one of 64? So me thinks. It makes sense. With those values, the 2g MAF will flow 20-30% more at any given Hz than the 1g MAF, which is widely known.

I think the confusion is between what is hex and what is decimal.

Hex ---> Dec
40 - 64
64 - 100
8C - 140
140 - 320


So if you're running a 1g MAF (why would you still?), use the 1g values, but subtract 40. If you're using a 2g MAF, use the 2g values but subtract 76.


Now is this referring to the MAF size (size*100)?

Hex --> Dec
5E86 - 24198 (214.98)
62B9 - 25273 (252.73)
7A03 - 31235 (312.35)

I'm curious where the 286.0 value I'm using for the MAF size came from if these are indeed refering to MAF sizes.

I wish I knew how to disassemble ROMs and read all this stuff for myself. Maybe once school starts up I'll dive into that some more.

On a side note,
I'm running the MAF scaling that is basicaly the 2g values minus 76 and that has me at good fuel trims. I've put more than 1000 miles on my car in the last 2 weeks. (I got 27mpg highway while drivingthrough the mountains ) I'm driving from Pittsburgh to Philly next weekend.

The 286 came from the 99 eclipse ROM. I must have totally overlooked that he mentioned them as HEX values! IDK why I thought I looked and thought it was decimal.

 

7A03 is the MAF size.

The scalling for MAF size in ECU Flash is x*600/65536. 7A03 in dec is 31235. 31235*600/65536 = 286

 

so we're adding a hex adder to a scaled "g/s" MAF scaling value when people rescale their MAF's? Seems like we should be using the same scaling for both to do that properly,no? This is referring to the Evo-m 'how to rescale your MAF' thread.

 

I just looked:

The scaling I worked out for the 2g/Evo3 MAF is:

57,57,92,106,114,119,124,128,132,136,139,142,144,1 51,154,156,159,158,156,155.

This is technically correct and works well on my car.

 

The MAF scaling value is not scaled, it is a straight decimal value and we add the decimal value of 140 to it.
The MAF size is scaled though.
