The Idea was brought to my attention first by Skunk about trying to get the eco to work with the ld9 reflash just as the 2200s can.
Now my question is, does the map sensor matter? The ld9 reflash is for a 2bar map sensor and the M62 comes with a 2.5 bar map sensor.
Do you think this will cause any issues?
I'm willing to give it a go around. If it works, it works. If it doesn't, it doesn't but is still worth a shot.
so does a 2 bar and a 2.5 bar map sensor make a difference which one is used?

I have yet to get an ECO to take the reflash...

I don't know exactly what you are asking, but all GM map sensors read 0-5v. So, you can't just switch map sensors and expect the tune to work well. You have to scale your VE values to coincide with the new sensor's pressure to voltage relationships (e.g. fake a 2.5 bar).

.... no one is faking a 2 bar here but thanks though and yes I do know since I have been tuning for quite some time now but thanks for the input...
I was asking, If a tune that calls for a 2bar map sensor meaning the tune only reads up to 200 KPAS. What would happen if I wired up a 2.5 bar that reads beyond 200 kpas. Would it still be possible to use a map sensor that reads beyond 200 kpas even though the tune isn't meant for beyond 200 kpas.

Wow... you simply have no clue do you? And you have been tuning for about a year or two with Aplha-N...I don't consider that"quite some time." So, before you think you know everything or are going to write off good information from someone who isn't Ron, Chris, Jeremy, Brian, etc., reread what I wrote.
Map sensor readings for ALL GM sensors range from 0 volts to 5 volts regardless of the map sensor you have. A 0 volt drop is the lowest reading of pressure for the sensor, while 5 volts is the highest reading. So, YES you can use a higher value pressure sensor, but it does not have same relationship between pressure and voltage as a lower pressure sensor. Your PCM reads voltages, not pressure. The Jbody speed density tune does not allow scaling to accomodate using different pressure sensors, so the only way to get a respectable tune out of it with a 2.5 bar sensor is to use the 2-bar tune and scale your VE and spark values to represent a 2.5bar
WHICH IS FAKING A 2.5-BAR TUNE!!!

lol relax buddy. you went into a large drawn out rant for no reason and I take everyone into consideration ( even thought I don't know who half those people are you listed, so it sounds like a personal issue there) so don't cry please we are adults. That's all you had to say. If that's the case then I'll use a 2 bar map sensor to make it simple. Which was my question and that's All you had to say I don't need to fake a 2 bar, rather do it 2 bar or Alpha -N. I don't know everything because If I did, I wouldn't need any info from the org.

that's about two years with Alpha-N, One year with Ecu+, One year with Dsm Link, and one year with MS on a ford probe gt 2.3 turbo...
please don't question me when you have no clue either...

I set up my own MS-II and have been tuning speed density on the Cav for nearly 2-years. I know how the @!#$ GM sensors work Vega. If my name were Ron Beyer would you listen to me then (hypothetical question because I know you would)?

no i believe you. I'm just saying don't tell me I haven't been tuning.

fair enough.
HUGE misunderstang on my end then. Sorry.

LOL no problem case resolved. now if you do know gm sensors so well, that means you'd be able to get hands on a 2 bar + the harness right?
or answer me this, is the 2 bar the ld9s use the same as the 3800 2 bar? and if so how do you wire it into the ecotec harness?
I don't know the physically characteristics of the weatherpacking for 3800 MAP sensors, so I don't know if a 3800 plug is the same as the 2.4L SC plug. However, MAP sensors are nothing more than a strain gauge (potentiometer). So a 3800 2 bar should have the same circuitry as a 2.4L 2-bar and therefor the same voltage-pressure relationship. I have never seen an ECO MAP sensor either, but I will venture to bet they too have 3 wires going to them. One wire goes to ground another to 5 volt DC and another is the measured signal. If I had my Haynes manual with me, I could tell you for sure, but I'm at school and won't be home again until next weekend.

02 2200 has the same physical pcm as the eco and it works on them?.?. This is why I thought it might work w/ the eco.

Interesting - any feedback??
we will see once someone or I, can get hands on the 2bar map sensor from an ld9 and the wiring diagram + harness
A long long time ago I tried the fake 2 bar and we just couldnt get the car up and running
1989 Turbo Trans Am #82, 2007 Cobalt SS G85
this wouldn't be a fake 2 bar in this instance, I'd be using an actual 2 bar ld9 s/c reflash file to work with the eco pcm that skunk came up with and an actual ld9 2 bar map sensor. Then proceed to tune the actual car with fueling and timing tables up to 200 kpas.
Good luck guys, there will be a 40oz Double Malt in the mail for the first to make it work

getting together a few pieces to try this out hopefully this weekend while I also install my suspension.
Well let us know how it works out for you.. It would be really cool if it does work. . .

From what i've been told from a couple people on here, the SC reflash
is a fake 2-bar, just GM did it for us instead of us having to rescale everything from scratch.
Not sure if that puts a crimp in your plan or what not, but this is just what i've been told.
Good luck with this shiznit lol. The eco ECU is what made me decide to go LD9

In an way it is.. The tables have been halved, but it does read boost. (IE:fueling would now be controlled by MAP instead of TPS)
