Base timing interpolation of stock ECU optimized igniton for AEM EMS... TUNING

[Greg E]

So purge is just a fuel compensation off the the MAF or Map voltage then? It would seem like purge opens to generate a kpa drop. In my mind I'm thinking the bleed off effectively results in a density drop and a 10-20% kpa shift to move the ecu into to a more conservative timing number on the base timing map?

In the OBD2 cars, they switched to a PWM solenoid for the purge and its driven by duty cycle just like the BCS.

At idle when vac is at its greatest, purge duty cycle is about 100%. As RPMs and load (airflow) increase, the purge duty gradually reduces to 0. At 70 load (about 0 psi), the purge is completely deactivated. There's a few other triggers which also disable it and that when Accell Enrich and Decel Enleanment are greater than a certain value (basically during moderate acceleration/Decel).

There's a second 3D (rpm and load again) table for the purge which I believe to be fuel compensation but I haven't quite figured out what exactly the values in this table means. The look up value from this table get tied in with another word value which is then Tied in with yet another value which is associated with IPW. This is why I believe it to be a fuel compensation value.

I've haven't found any tie ins with ignition timing nor the MAP sensor for this system.

The EGR functions the same way. 3D table lookup which is the base duty cycle value. The only correction for this system is a simple 2D table with a single Load axis which contain the MAP sensor offset values. No tie in with fuel nor timing in this system.

i dont want to go back and forth with you. my point still stands. arguing online is retarded. good luck with your projects and have fun

Fuck you bud!

Was that in jest to Broomfield or are you going for the 3SGTO Nelson award?

[SnakeSkinner]

my god this is a waste of my time. this is like 3si used to be years ago.. im not really sure whats going on here or what your trying to prove. ill reply with cliff notes of this thread

very good point, threads like this (and posting a dyno chart of a twin turbo V8 and saying it was a dyno from his 3000gt) is what got this guy banned from 3si. He loves to try and make people think he is smart and loves to tell the people that really do know what thy are talking about that thy dont.

Arguing with this guy is like trying to argue the Equilibrium Theory with a 5 yrs old, he has no idea what he is talking about and no matter how many times you prove him wrong he just does not get it. I spent plenty of time arguing with this tool on 3si before he got banned, it's a waist of time.

And Ray was all like

[Alan92RTTT]

Fuck me? Who the hell are you? No need to take out your e-rage on me, you act just like drmbldr did lmao.

You do realize that J Fast == drmbldr

Same stupid, new name.


Wonder if its time to put him into the same group as steve68

Real McCoy pmed me about that last night.

I just hope we haven't lost the opportunity to see Ray's 5000 rpm lawn mower

Thank you, Ray. I enjoy them and always try to keep it real. Enjoy your car as well.

WOW, first post and visit to 3sgto.org since February. The king drops by to troll. The members here should feel so blessed by your presence and time given to this board.

I'm going to go play some more, enjoy the fruits of my labor, and post less. Back to racecar... have a good one.
