HellFire Status & release date annouced

Recommended Posts

1. As a research tool, it's another sanity check on calibration of the AFM. My flowbench gives a number, this MAF gives a number, and the AFM gives a number. In theory, they should all agree. That's what I'm studying currently.

The results will be very interesting. People have built MAF conversion kits for other brands, like BMW, but nobody has really quantified the benefits. It seems like the MAF should have better resolution at the high flow end, allowing better fuel supply control. I get the impression that the vane-type systems just add lots of extra fuel at the high end because when the vane is pushed open large air volume changes only cause small vane movements. If you could compare that between the two, and response rate to opening the throttle, that would be very cool. Pulsing of the signal would seem likely with the vane system also, something I believe the weight and the balance chamber were intended to damp.

Nice update Len, glad to hear the progress. That's also funny you mention HEI TomoHawk. Yesterday I wired in a GM HEI with a MSD coil and now I have no spark. So that's today's project.

I did mine with a HEI module in the TIU housing and a Petronix Flame thrower II (0.6 ohm) coil. Working perfect since day one. Very happy with it. You sure you wired it correctly? If its under the hood, did you disconnect the plug at the TIU? It could be messing with the HEI module. I have a thread on the mod here. If you need more detailed photos, let me know.

we're all waiting... i believe the components and knowledge are plentiful, but with a new baby in the house the one ingredient in short supply is time...

 

but my z has waited over 30 yrs. for this upgrade and i'm sure it can wait patiently a little longer!

Well, my search for the one-sportscar solution to our two-sportscar household is not going well, so I imagine I will have my '78 for a while longer yet -- perhaps even long enough for Lenny's daughter to tell dad to get back to work on the Hellfire! :P

Hey Len,

 

I'm still keeping up with this.  When it's right for me, I'll send you my ECU, a case of your favourite, and a blank check?  ;)

 

  We are chatting here now, instead of HybridZ, so if you like, I usually hang out here for a while between 6-9 eastern.  Spread the word about CZC chat, because Mike is a great guy to chat with, but aren't there hundreds of  registered/regular users lately?

Hi all, just a quick update. My daughter just turned 10 months old a few days ago. Holly cow, time flies! I was out in the shop this weekend moving stuff around so I can try to get back to work on AFM and HellFire calibration. Wish I was further along. I haven't been loggin in much lately, so ping my email if you have any questions that are time sensitive rather than pm. Chastising and harrasment are welcome. :)

Let me start...

Good thing you didn't announce which year

 

Hahaha!! :)

Best of luck with both of your projects, the 10 month one & the electronic one ....

Hey Len!  Welcome back!

 

So I had suggested to you a while back that I might be selling my  '78 and buying a '79-'83 T-top ZX (for the T-top and little else, as I love my '78).  Well, the challenge seems to be finding a good, rust-free'ish specimen of ZX.  I've not made any good progress and don't anticipate finding anything this year or next... or the next after that.  So you can still consider my '78 available for beta testing.

I am fortunate to be in the beginning stages of my resto, so I can wait a while for this. BUT, it would be great to have it tested and proven on the street while I'm waiting!

Just checking in to say I'm still alive. :) Still not a lot of progress on HellFire, but I'm seeing a little bit more shop time around the corner.
