anyone interested in some o2 sims or an controller that can add or subtract fuel and ignition timming

the o2 sims will work on any car and are 30 bucks each + shipping which should only be 2-3 bucks\and are 3 wire hookup work with single wire threw 4 wire sensors

the fuel and ignition controllers are still under development and but will allow adjustment of fueling across the map of +/- 10% and the ability to reatrd or advance ignition timing -/+ 5*

testing should be done soon on the fuel/ignition boxes

please note fuel.ign controlers are not substitues for complete computer tunning but give u the ability to adjust to a point the stock tables or even the tables on a modified chip

How/what would a O2 simulator be used for?

the o2 sims are used on 96 and up cars when the cat is removed or off road pipe is used,

without the cat the rear ( downstream) o2's will set of a check engine light so the sims just trick the ecm into thinking that the cat is there and working correctly


they are a lil useless on our cars but i figure ppl may have other cars that do need them

on the other hand i am building the piggy back controllers specifically for the 3rdgens

Will the fuel and ignition controllers work in our cars? If they are cheapish I'd be intrested

lol i edited my post after u replied and i figured u were going to ask that ?
yes i am building the piggy back controllers specifically for 3rdgens one for maf cars and one for speed density cars (v6) and v8 versions to follow.

think apexi afc except these dont have digital displays and the price will be far cheaper then anything available for what it does

If the price is reasonable, i would be interested in the fuel controller.

Updates on the fuel/ignition boxes?

the maf circutry is giving me some fits so its slow going on those so it may be some time before i have a maf based controller ready but sd version is about ready to go

on the other hand ive figured out a way to get the sd cars to read boost using one of my controler but it does require burning a new chip with updated fuel tables

basically i can use a 3 bar map and cut the output signal down threw the controller.the map resolution goes down doing this but if i could come up with a chip to include witht he controler it be a pretty easy install for somone lookng for boost

once i get the maf circutry figured out and fixed i could basically extend the mafs useable airflow range as well
