Stock Computer based Management systems

[turbolc2]

What are the known strengths of the newer stock computer based systems such as Red's new MAF sensor,Bob's Translator + & Steve's new MAP based Maxeffort?.If you've had testing experience spill your guts.Even if you don't have 1st hand experience,put your thoughts out .Makes for good 07/04/02 reading.HAPPY INDEPENDENCE DAY!!!

I haven't run Red's new MAF, nor Steve's stuff. I have run the Translators, and Late MAFs. I've also developed an actual ecm bench and have hundreds of hours running programs on it. I've also modified some ecms so that they no longer have any hidden code, in them. Rather then being limited to just changing the prom, and part of the code, I have developed actual source code for my ecms.

I'm also a petulant old phart.
I'm not all consumed with 1/4 mile times, but I insist on perfect drivibility. No hiccups sneezes, or any bad manners. Using 55 and a 60 turbo, lag is not in my book, or tolerated.

I've gone to a blow thru MAF, and for a long time was running extender chips. The lean cruise, A-T, launch assist are all grand features.

In the last few weeks I've actually figured out the scalers and MAF tables, and am now working on understanding the real workings of the LV8 stuff.

As of yesterday, I have the flow results of various MAFs with and without screens, and now with my new understanding of how the MAF calibration works, I'm tayloring it to my proms.

With using EEPROMS, being ROMless, and with an injector driver change I don't see where any ecm has anything over a 148. And with a Translator Plus, I can do fine tuning faster, and as accurately as any aftermarket ecm.

So far one other benefit, is that I have a whole new TCC logic. The car really acts like a 5 Speed now. A sudden TPS unlocks the converter, unlike the % TPS stock stuff, no time delays, no TCC retard, no min unlock speeds that are gear dependent, or silly stuff invented to keep granny happy. LOL

I also have a DIY data logging system that is 15 frames a sec, and has 4 addition channels. Also a DIY-WB.

Lets see, $50 ecm, $300 for the T+, $120 for drivers, $200 for a WB, and $60 for the data logging. $ for $, beat that........
yes, I had to learn to solder, and still learning to read code, but I sure saved a bunch of money.

Least we not forget those that have fought for our Independence.
Happy 4th

I think dollar for dollar the max-effort is best set up . I think that everybody wants his new mass air less set-up. I beleive that for most all street driven t-r you don`t need it. I know of atleast 5 or 6 different people that have 9s with a mass-air and max-effort is made to work with weak or rebuilt mass-airs. I beleive that if you run race gas you can`t beat max effort. As for Reds mass air set-up it maybe the set for the future but you still have use 02 sensors and it will affect the drivability when they go bad !Laz

If the stock knock control system is good, would an individual cylinder knock controller be any better?

Great topic...great replies!

What really needs done at this stage is some accurate testing.

Someone just really needs to sit down with one of your devises, and hammer things out. LUCKILY, I have a coil near plug conversion on my GN, so I could answer alot of guestions accurately about what exactly the GNs need, and could use.

I wouldn't mind doing the testing to see what gains your system would allow for on a GN. While not a full out race car, I can do 15 frame/sec data logging, and have an extra 4 channels that I can use for extra inputs.

It would be an interesting experiment.

Send me an email, and we can talk it over. I have a couple of pre-production units gathering dust.
