EPROM Pics and IROC Engine Pics
I put two photoalbums on-line today. One is a photoalbum that documents my current Head Gasket R&R activity. These pictures clearly show how the MiniRam causes the back cylinders to run rich compared to the front cylinders. I also have a lot of Orange color on my Spark Plugs, Piston Tops, and Head chambers. Does anyone know why?
The other album has pic of the three ways to run a custom PROM....
1) Install a ZIF
2) Use a HyperTech/Jet adapter
3) Program the EPROM that is in the MemCal
The photoalbums can be found here....

I know someone will disagree but I believe its an additive in the gas. I think its called mmt? If im just light cruising my plugs get orange also. And people were arguing with me about being able to control indvidual cylinders!!!!! Now you know why I said it it would be a benefit, especially with the mini ram, my rear cylinders are black also.

I wanted to post Bruce's (Grumpy's) response since it is very informative....
The color you call orange is normally referred to as beige / light brown, normal with conventional gas. See how there is no carbon (orange <g>) at the sides of the pistons? That is where your gas washing the cylinder wall and removeing the oil film
the rings need to transfer teh heat off of them, and to prevent excessive cylinder where
Trash them plugs, look how the side electrodes mask the spark from the chamber (also explains all the timing the engine acts like it wants), poor intial flame travel. Like I said cheap ol autolites and read em often, maybe not all bit at least
some. Saying 6+8 hard to get to isn't valid IMO, I had angle plug heads with the
Edelbrock TES, and even with my back could easily do them. All the plugs are a tad rich. Plugs do look to have the noses of the center electrode knocked off (had to
guage how much in these photos). Down a little in fuel, good autolites, indexed .030-.032 gap and have fun. If the Ignition system is up to the task.
Ultimate rear end, well matter of opinion <g>
remember my comment on knocking the corners off of the pistons?. This shows phase 1 on that happening.

As an example.
The GNs also are noted for this.
Please note the ones complaining there are also running 160 stats. Run an engine to cold, with at too warm plug, then you have to use too much fuel, hense the tune is less then optimim.
I run a 195, and guess what?. No problem.
I've also, never had a serious enough problem, where distribution was a problem, on any street engine, that I've tuned.
Try looking at a dual plane with the heat riser plugged off, please note that you have 4 pairs of plugs that burn the same way.
Two things, injectors are a whole lot more even then carbs., and that would infer that carbs are even worse, and they aren't.
So that would tend to point that metering isn't the cause.
We again get back to what the engine wants verses tell it something.
Everything is designed to run at around 200dF, and when you get away from that you can *momentarily* make some HP. ie Going to compression ignition. But for a street engine, everything from piston fit to head bolt preload suffers. And tune
Again a very short explaination for a issue that covers chapters
I have to say I didnt take into account the coolant temp playing a role. My car does run cooler than 200df. And I know that having higher temps makes for better distribution and ring wear. Dammnit In a year Ill be a M.E. and I didnt even think of that.

I just checked out your photo album, in particular your EEPROM photos. The are very clear, shows all options. One that I am considering is to desolder the stock EEPROM and just put a 28 pin socket in its place. Why do you need a ZIF socket there? I think a regular socket would hold the chip better. Correct me if I am wrong!!

Mike,
Using a ZIf just makes it easier to remove/install the chip. You are correct - you don't need a ZIF. You can use a regular socket that requires insertion force. However, the ZIF just makes the chip swapping easier without putting undo pressure on the carrier.

Using a levered ZIF can run into interference with the 165s.

Traxion......I was curious how you clip the memcal holders on the computer. I ordered the zif socket, installed it, and the eprom, but couldn't push the memcal all the way down without the holder clip interfering with the zif socket. Any advice on this!

I tried a zif but It hit the ESC filter and I did not solded it in a was scared that if I bent the ESC filter over it would break! I used a 28 PIN dip and it works well. AMD chips are a little wider than most but they will fit you just got to be careful!
Traxion? What kind of Spark Plugs are you using?

David,
I'm a little confused ... 'clip the memcal holders on the computer'? I am not following. You will not have to modify the computer at all - just the MemCal.
Dean,
I had to file one end of the ZIF down so that it would clear the ESC filter. I should have stated that but I forgot
I was running Bosch Platinum+4's. But, I will be switching to either Autolite or ACDelco plugs. Rumor has it that most of the serious tuners use Autolite ... cheap, reliable, and work very well.

He's probably talking about the blue cover. That wont fit after you put a ZIF on the memcal. So dont bother with it, just leave it out

No I'm not talking about the blue cover. When you insert a memcal in a 730 puter, there is a little clip or tab on both ends that fold up as you press the memcal down and then it sorta clips onto the memcal. It keeps the memcal from coming out the socket. This little tab or clip interferes with the zif socket.

David, that must be one big ZIF socket you bought! I have no problems getting those side clips to hold down the memcal on mine. I used the same exact ZIF that Tim listed on his website. Still couldn't fit the blue cover over it, so I sawed it in half and glued it on over the netres chips. The AMD chips I bought aren't any bigger than the other chips I have either. Of course, they're 27C128 chips, but I don't think the 27C256 chips are any bigger...

Hmmm...I bought the same ones that Trax listed on the picture page. I'll try it again but it seemed like the tab wouldn't clip onto the memcal when I pushed it into the computer as the zif socket was in the way.

Nevermind. I just trimmed the top edges of the tab and it fits Ok now.
