How does translator add or trim fuel

[BJM]

I don't understand how this works. If the MAF translator trims or adds to the actual MAF signal to fool the computer, wouldn't the BLM just adjust for the fact that the MAF seemed wrong?

Even at WOT, wouldn't the newly trimmed BLM numbers just undo the MAF adjustment.

Also, If I don't hook up the ignition module wires yet (because I am in a hurry to fix my car), would the translator have any clue as to the engine speed for adjusting the fuel?

The Maf doesnt tell the computer if its rich or lean, it tells it how much air is flowing. So if it tells the ECM the car is using more or less air than it really is, the computer makes adjustments. At WOT BLM's are locked at 128 so it doesnt make any adj. in most chips

I believe the WOT BLM at 128 concept, but how does idle fuel get adjusted. The translator makes no comments about having to have an open loop idle type chip or anything. Any ideas?

Seriously, this sound like a question for TurboBob.

It's all done with "smoke and mirrors"

The only thing the Translator does, is translate the "chevy" language coming out of the chevy MAF to language the ECM understands as "buick". No magic, and it works just fine.

Where the complicated algorythms come into play is when you throw the Extender chip into the equation.

I didnt think Al Gore had any rythem!

You're right he don't.

I beg to differ,
the Translators are alot more.
They are magic.
If you play around trying to improve on what's in them you quickly see, it ain't child's play.

Get some serious datalogging equipment, a WB, and try to improve on it. It ain't easy. Bob has done his homework on this deal.

The Extender Chips just increase the level of genius.

At idle and in closed loop your mixture won't change unless the blm's were pegged to begin with. For example, if your idle blm was 112 and you tweaked the translator settings to get it to 128, the fuel mixture is exactly the same. The ecm just has less correction to do. At WOT, no O2 feedback is used, so if you alter the maf signal, the mixture will change (with the extender chip). If you don't have the extender chip, WOT trimming won't do a whole lot, but it does still seem to affect medium and high airflow numbers some.

I didn't really mean to "simplify" what is being done in the Translator.
Those that have them can look inside, see that "big" chip. It's actually a full on microprocessor. So no, it's not simple, but most of the work that's being done is "translation", hence the name.
