CD Deception - Will It Work - Toyota Camry, 2.0L, 1989

Fuel consumption has increased for a long time. I changed the candles, set the lead angle, changed the filter ... nothing helped. poking around on the Internet, I decided for myself that the matter could be:
1 - the catalyst does not behave adequately.
2 - to the CD sensors the end came another 200 thousand microns back.
3 - when the guts were changed in the automatic transmission - no one thought about the compatibility of the brains.

Naturally, it was easiest to deal with the CD, and the process began. Searches on the Internet + rumors about "bogus" did their job. Two directions of work were indicated:
1 - to clean both CD with acid.
2 - come up with a solder from resistors, capacitors and whatever else, to simulate a working CD.

1 - gave the result - from 17 to 10 liters. by 100.2
- in the process, you need to decide on the pulse length.
