Going through the sema products page and found this lil ECU to replace the MAF on FI cars. It says it can be used on any MAF based car to run it in speed density.

Heres what it says on the page..
The MAP-ECU (Manifold Absolute Pressure Electronic Control Unit) is the most powerful piggy-back speed density conversion device on the market today. The MAP-ECU is capable of running on most any modern 1-16 cylinder EFI vehicle using an intake air metering system (Hotwire, MAF, Karman-Vortex, and MAP). This small (3”x6”) electronic control unit packs a host of features normally found on more expensive and complex stand-alone EMS systems. However, the MAP-ECU works in conjunction with the stock ECM to give the day to day driveability needed for a street vehicle while allowing end user fuel tuning. The MAP-ECU replaces all supplemental fuel computers and allows you to tune the vehicle for larger fuel injectors, larger camshafts, revised intake configurations, or aftermarket forced induction systems. It’s perfect for forced induction conversions where the factory air metering system is unable to cope with increased airflow levels. The MAP-ECU allows you to completely remove the factory air metering system and run a more forced induction friendly speed-density system. The powerful windows-based MAP-CAL software allows the user to map the airflow voltage on a scale of 0-8000 RPM and -10 to 30 PSI. MAP-CAL also packs numerous tuning features such as data logging of major engine parameters, NOS control, two auxiliary outputs, and wideband O2 sensor support for popular aftermarket wideband controllers.
The MAP-CAL dashboard allows the user to monitor critical engine data such as Air/Fuel ratio, RPM, boost, throttle position, and airflow in real time. Using MAP-CAL the tuner can make changes to the fuel mapping in real time using a table or 3-D Graph. MAP-CAL logging allows the tuner to log each tuning session for later comparison to each run, making tuning much quicker and more accurate. A basic installation of the MAP-ECU only requires connection to 5 wires at the stock ECM, and the installation of the external air temperature sensor unit.
The complete MAP-ECU package includes the MAP-ECU, 3’ unterminated wiring harness, external air temperature sensor, complete user manual, and MAP-CAL software on CD ROM.


Seems pretty interesting whaddya all think? Answer to our maxed MAF problems?

 

Interesting J my man, I am gonna have to try to read it tomorrow. I have been drinking Fighting **** and I cant think straight right now, LOL.

 

Yeah seems cool enough, don't make me post the CO2 powered turbo link....for those who think the STS kit is funny(which I don't so don't start bashing me STS owners )

I've been bored tonight too, almost to drinking my boredom away too, but instead i've been going through the sema page and posting my findings....pretty slim pickings for us LS1/6 F-body guys so far.

Cool, what kind of poison have you been drinking?

 

You are drunk! I'm almost to that point but not yet...no drinking for me tonight. It's me and my lil son, he's watching drag racing/street racing video on the other monitor right now....he's only 21 months old and he is obsessed with cars He's driving me up the wall its all he wants to do, either go outside and look at and touch the car or watch my videos on the computer....but back on topic my drunken friend, but take it easy on that stuff.

Yeah my 3 year old boy loves cars. I take him in mine and just blip the throttle a little and he wants more haha. He thinks its the coolest thing.

 

Cool, got him started out early on hotrods thats good Now, this comment is related to the CO2 powered turbo, wasnt there a prototype of a turbo that is moved by hydraulic fluid? I remember reading about it.

 

sounds a lot like maga squirt, a DIY fueling solution. in fact i think it is magasquirt but just assembeled for you and put in a nice case. there are a few local guys running it around here and i am just now aproaching the need for such a device.

i am told you can get mega squirt for aprox $170. sounds too good to be true but maybe not.

 

Hellraiser thats awesome and I know all to well. I think it was from blasting around in the car with his momma when he was still in the oven. He came out loving the car and its sound

Brandon, don't know about the hydraulic powered turbo...never heard of it. I can see CO2 spooling up something as it is stored at some rediculous pressures but...it might be good for a short burst o speed...who knows.

Parish, can you post a link to the mega squirt. I've never seen it. Sounds pretty interesting. That device I listed above is like 860 bucks But I would prolly pay it to tune out the MAF reliably and easily on a FI app.

i am just now reading up on it, http://www.bgsoflex.com/megasquirt.html

there are a few guys running it localy. an 11sec turbo bemer, a 400hp turbo probe, and another probe.

sounds like it can be used as a complete stand alone or piggy back. i am just looking at it do the fueling.

 

this is a link from that other page, very interesting! http://www.bgsoflex.com/megasquirtspecs.html

 

Thanks buddy, going to do some reading now

 

The megasquirt is cheap and effective, but it is really a project to assemble and use. A guy I know used one when he built a supercharger kit for his Mazda, and it took him a few days of soldering. If you have more time than money, though, it can be a great solution.

 

the guy that is doing it localy is saying it compares to wiring up a car stereo. he also said it took him less than 4 hours to assemble his first unit. he is a prety smart guy so who knows if it is really that easy. i think i am going to give it a try.

 

I might be missing the point here, but why do you need this extra controller? Lots of guys on HPT (and this guy, not to put to fine a point on it) have removed the MAF altogether and converted to SD using programming alone. Besides having lost 3 mpg, and it might be to early to tell on that -- lots of logging runs atm, it seems like a great solution (works and is free). Is it simply a matter of replacing the MAP with a higher pressure MAP?

 

HPT? do you have any links. as far as i knew no one had figured out a way around the maf limit problem.

 

He's talking about HP tuners, Yeah you can go to SD with Edit or HPT but this adds a 3 bar map sensor so your fueling is always taken care properly...from what I understand...

 

come on post the CO2 turbo link
That should be good for a laugh

 

....hey I might get one or two to add to my s/c

 

This device appears to similar to devices made by a Japanese company HKS.

There's a detailed explanation of the vein pressure converter (VPC) by HKS and ETAS LA 3 device (probably same as in Innovative LM1) in 'Supercharging, Turbocharging, and Nitrous Oxide' by Earl David and Diane Perkins-Davis.

It appears (and I'm a novice) so speak in general terms that speed density devices work better with FI than MAF, unless you use a device like the VPC as a controller between the PCM and the sensors.

I've tried to digest No-Go's explanation of the VE tables but still get lost when he and others suggest reprogramming the PCM to SD rather than mafless.

It would be easier for (the mentally challenged like me) to buy a device that figures out all of the calculations on the fly while driving as this device (or a VPC) suggests it can do.

The issue is whether it will snyc to the PCM in our cars.
