Questions About Pro-M

[SeventyMach1]

Well, I have an opportunity to grab a slightly used Pro-M calibrated for 19 lb.'ers. (for cheap, I think).

1). Will it help my car now (I currently still have the stock 19's)?

2). Can I send it back to be re-calibrated when I need to in the future (for 30's)? Even with the "new" company?

3). Is it worth $75?

buy it,75 is a steal.you can send it back to get it recal'd anytime for whatever size you want.and yes it will help with the stock 19's

the pro-m housing, you can actually recal it yourself by changing the sample tube. People complained about them in the past, but i ran one for a year, and had no problems at all, maby because i had it cal'd for 19lb inj's

you can get it and then get an optimizer when you get 30# inj. that way you do not have to send it back it is plug and play man!

Your thinking of C&L. The Pro-M's must be sent back for recal unless like Tony mentioned you get the Optimizer. The Optimizer isn't under $100 though.

1. In your current combo condition, the 19lb caled maf will help none or a couple of hp at the most.

If the cal is a bit off, it might even cause a slight loss as opposed to the stock maf because the oem maf curve is usually very accurate.

You just aren't moving enough air at this time to warrant a maf change IMHO.

2. Sure! IIRC, the recal price was around 100 bux

3. I would not spend 75 bux for a no gain mod
but
If you would have 175 total in it ... is that cheaper than what you could find a used maf with the cal you need later on?

btw, 77mm & 80mm meters are more accurate than the Bullet 75mm meters.

i say go for it them suckers are kinda expensive. If not buy it and sell it to me lol I'm been looking for a cheap one for 19s what size is it?

 

[SeventyMach1]

It is the 75mm Bullet ..... so what do ya' think Grady? Yay or nay?

Still don't think you will see much if any gain
and
maybe you would get more for the 75 bux on a different mod

Look for a post around a month ago where Don 95Vert and I were talking.

He has interesting things to say about several meters
and
if you don't know it ... he is a Pro Tuner and has lots of experience with mafs and ... even more importantly ... how mafs interact with OUR 94-95 cars

I dunno grady on a dyno my car picked up 8 rwhp when I replaced mine but what happened was I had the chrome one and when we dynoed the car it made less power because it was running lean for some odd reason when I switched it to the stock one I got the power back and when I used the plastic one of the 75 mm bullet it made 8 RWHP over stock.

My car sucked with the bullet 75MM meter. The 77MM cleaned things up tremendously. My tuner had an easier time with the dyno session.

Hey Tony

You bring up a good point and I would like to say a thing or two about your experience and others in general when upgrading the maf.

If one just bolts on a maf with no way to fine tune its transfer curve, they take their chances on:

1 the accuracy of the meter as delivered
2 how it interacts with intake pipe or cai
3 how it interacts with inj's

As with most things, the maf is gonna deliver performance in a range of maximum and minimum for the above examples.

If 1,2,& 3 are the maximum, the gain will be the greatest
If 1,2, & 3 are the minimum

In the case of a stock or close to stock combo .........................

One is not moving much air at all!
Not even enough to warrant an inj upgrade!
Again, if were are talking about no pcm access here ...................
I'd wait until air flow has grown to the point that larger inj's are needed and go with a maf at that time

then again ... Tony got 8rwhp ... what do I know?

Bottom line is, IMHO ... the results can be one of those ...........

It Depends Upon ...... kinda things

thats right grady like they say all our cars are different what might work on my car may not work on yours its countless hours of tuning dyno sessions and alot of time taking things on and off the car to see what it really gained but from my years of racing its always a learning curve. You will see something that will blow your mind away almost everytime I go to an event and it makes you go hmmmmmmm. And or sometimes you do aloyt of this like I did last year at Fun Ford Atlanta !! LOL! Good luck bro!!!

I would say get it now b/c of the price. You can always hold off on using it until you need to. I have quite a bit of parts that I've bought new and used but have not yet installed. Waiting for the right time and need. I bought the parts b/c I knew I'd eventually need them and the price was right.

 

[fiveotony]

Justin I would say get it and then try it. Go to a shop with a dyno dyno it without the pro-m then try it with the pro-m and see what happens make sure you have an Air Fuel ratio and see if it runs lean or rich or stych.

 

[SeventyMach1]

Thanks for all the input guys. I'm gonna take heed Tony & get it tomorrow. I'll be attending a dyno day Saturday, so we'll see. AFR costs a little more, but oh well.



Paul, that was my exact intentions if I got a decent feedback on this. I have so many parts lying around for the future, it's not even funny.

 

[fiveotony]

it costs a little more but it is mo cheaper than running too lean let us know what happens.

Hey Justin

The great thing about that price is

if you decide you wanna do something different

You can always get your money back

Looking forward to how it works out for you
and
I hope you get the maximum amount of gain possible

Well ,I never made it out to get the meter .... so I just told the guy that I wasn't going to get it. I'm just going to wait & get exactly what I need.



If anyone want's it, it's up for grabs. The guy is here in NC. I don't know if he would be willing to ship or not, but you can ask. His email is [email protected] . I told him I'd try to help with the sale.
