Back when I was here regularly some people were starting to use these sensors as replacements for the stock LT1s when they went bad.

Well, after blowing mine out from a nitrous backfire I am looking for a replacement.

Except I can't find a place that sells them with the LT1 harness. I already have the table conversion values to use with TunerCat from someone on the board.

Where can I find this sensor and conversion harness?

 

been a while and i'm at work so i can't look, but i think ls1speed.com has them.

 

check your P.M.

 

I'm running the Factory ZO6 MAF on my car, it requires a pigtail from Ramchargers.com, and a change to your PCM program to run the GM unit. Run it for over 3 years with no problems.

The LS1speed/grantenelli unit is supossedly calibrated for use on the LT1 engines, but I'm not sure about these units.

 

Ditto.

The pigtail you have to call/email ramchargers for since its not online. It was 18 bucks when i bought it.

I bought the z06 MAF from jason cromer, it was ~$130.

Only downside to the MAF is that on an lt1 computer it runs out of table at 330(somewhere in there) cfm. OBD1 computers will resort to VE tables after that, OBD2 stuff you need the most current definition file from lt1 edit and then you can change the MAF fail point code.

 

Seriously? That's not much higher than stock. My stock engine with custom CAI has peaked 310cfm! How can it run out of table when the OBDI PCM reads up to ~512cfm?

Thanks for the replies so far!

 

Lt1 tables only have the hertz input values 1488hrtz to 11216 hrtz. The Zo6 maf puts out 750 to 12000 hrtz. So when you scale the zo6 table, at 11216hertz its only 355gm/s.

Also i mis-typed above, its gm/s, not CFM.

 

On the Impala board it was recently reported that Dal is selling the f-body MAFS for about $130 it is a sale so I can not say wether it will still be that cheap but why deal with making the wrong part work when you can get the right one for the same price and have it read to a higher GPS.

 

Which work that way in your opinion?

 

Man thats called modding and hotrodding! Just because something didnt come on your car doesnt mean isnt right.

How many of you B body guys are running the F body maf? No different here, we are just going from 3.5 to 4 inch, instead of 3 to 3.5.

 

Correct many b-body guys run the f-body MAF it is easy to tune for and can communicate well with the pcm FAR above what the ZO6 sensor does. The ZO6 sensor starts sending info the pcm can not understand long before it's extra size is usable. Reread that last sentence, yeah it is beyond the pcms ability to read it before the stock sensor would have become a restriction. Meaning the only benifit it holds is price and like I said Dal has the stocker on sale negating that benifit the ZO6 HAD.

A lot of what goes on on these boards is people defending the mistakes they made, we could all get a lot further if we could admit imperfection. I tried the ZO6 MAF and several different tables all supposed to be right for it, I could not get it to work right and later learned about it's frequency complications when combined with the LT1 pcm. I was man enough to say I screwed up and sold it to a guy putting a 6.0L truck engine in a hotrod.
Even if you get this to work right it still can not work properly with the stock cpm to a level where the size is needed which means the stocker is better.

 

Could not disagree with you more.

The Zo6 MAF is far more accurate than the lt1 sensors. Since the hertz output is stretched, there are more readings in gm/s for the same given frequency range. This means more precise fuel control at all levels until 355 gm/s.

As for maxing out the lt1 PCM at 355 gm/s, it really is a non issue. You will NEVER hit that just crusing around in closed loop, unless maybe your car is heavily boosted. In that case you would have maxed the stock unit anyways.

After 355 gm/s means you will be running at WOT throttle. Preprogrammed fuel curve at that point anyways as it reverts into open loop operation.

Anyways sounds like you tried to program for it and werent able to and now have a sour taste about the whole idea? All you have to do is scale the ls6 program MAF table to fit the lt1 stuff.

It works perfectly for me and many others who have done it. Just because a stock MAF will read higher than the output of the zo6, doesnt mean that the lt1 isnt a restriction. Thats the most invalid point you have made so far.

 

Heres the scaled values (thanks to whoever originally posted them)

Thanks for the input.

Jared, would you be willing to export the four scaled MAF tables in TC and email them to me?

 

Ya no big deal, PM me an email address
