Then I unsoldered the prom from my memcal and soldered in a 27SF512 that I also got from moates.net, and burned may new bin to it. The 27SF512 is a flash programmable chip, so you don't need to erase it with a UV light when you want to reprogram it. So far it is working well. I have started my 4.9 a few times and code scanning works. I will know more after I get my cooling system filled and can run the motor through a full temp cycle.

Cool! Thanks for the info.

BURN2 runs $85 each. Thats a much better price then I have seen on other burners.

The 27SF512 chip runs $5 each. There are also several other devices that would allow running dual programs or easy chip switchout. Pretty cool stuff. And the price is not much more then having a custom chip burned. It will pay for itself the second time you use it.

I have been looking for a decent way to adjust my tune. Thanks for sharing.

in Texas they tested it as a 4.9L V8...I have no idea how they came up with the criteria to measure it against, but it failed several times last year before I got it to pass, but something still isn't quite right because its only getting about 15 mpgs.

If someone could give me a a starter kit and a 4.9 chip burning tutorial I would be happy to burn my own chip.

Also I would be interested in the injector removal tutorial.

What do you mean by "a starter kit"?

I will add the 'How to remove the 4.9 Fuel Injectors' to my swap in Tech tomorrow. With pictures. I don't want to interfere with Dizzixx's thread

I dont get the regulations from state to state. Either they are emission nazis (cali) or they just dont care (florida) then there are all the other states that fall somewhere in the category of clueless nazis that dont care. As far as I am concerned you put an engine that burns cleaner than the stock equiptment. As its an improvement so long as it meets the original standars it should pass in my book.

You said 4.9L v8. Do you mean they dont run a specific test for it as a caddy 4.9 v8, IE - the caddy 4.9 v8 with pfi in cars from 91-95 etc etc?

I will have to look into your thread as well Joe.

And regardless of how things go when I test my prom I will be looking into prom burning over the break between semesters.

quote Originally posted by johnsop1: What do you mean by "a starter kit"?

I meant a "4.9 chip burning for dummies" starter kit, where I could learn how to burn my own chips.

When I get my car tested, they ask the engine size and I answer, "4.9L" and they count the cylinders and record 8. The computer then figures out how much NOX and hydrocarbons are allowed. I have no idea where that number comes from.

The emission testing is a true patchwork. There are counties in Florida that do have testing, (Dade County) and there are plenty of counties in Texas that do not have testing. Eventually there probably will be one Federal standard, but we are far from that.

I am about 100 miles north of jscott in Texas. My county and the two sourrounding me do no emisssions testing. They do look for insurance,a catalitic converter, and make sure the brake lights work.

I second the how to giude thread as something I would be interested in.

Here ya go. 'How to remove the 4.9 injectors and Fuel Rails'

Hope it helps out

Dizzixx did you get the scanner to work yet?

Nope. Swapped out the prom for a stock one from a 92 deville. Neither scans. They both report on the scanner 'vehicle unresponsive' or something like that. It must be the wiring somewhere. I have no idea where to even start.

You scanning with key on right? No offence. Just covering the basics.

A8 is connected to aldl? If still doesn't work try switching the wire from A8 on the PCM to A9. Might be a bad pin or connection at A8. My PCM has at least one bad pin.

[This message has been edited by Fieroseverywhere (edited 12-15-2009).]

Yes I have tried scanning with the key on and with it running. Both to no avail. With the stock prom I was not able to get it to run for more than a few seconds, passkey or some other system I am guessing, so it was only tested with the key on.

Does A9 double as data out?

I will try that and see what happens. If i were to use a multimeter to read those pins how would I do that? I mean would I be seeing a change in voltage or resistivity or what, granted they are related but what should I be looking for?

Yes on the double out. At least according to what I'm seeing on the PCM pinouts.

Not sure on the multimeter test. I'll have to look into it...

No luck. Did not work using A8 on M or L.

If someone could meter a working setup and tell me what you see that would be helpful. I might try getting another box from a junkyard car and swap in my prom.

Bump. Hoping someone has some insight.

quote Originally posted by Dizzixx: My chip is a burn by rockcrawl (92 deville). He had problems flashing it as well. It took him two tries, so I am somewhat suspect that the chip is the problem. Without him around and given what someone said about stickpony there really are not alot of options. I wonder if I could get Joe (rockcrawl) to give me or someone else somewhat of a basic rundown on how to mod the values in the bin file to adjust for idle, wheel size, fan temps, etc. Unless of course you want to step up stickpony and show us that you can provide the same service reliably and in a timely manner. Not trying to call you out, just seems that there is a real opportunity here. People are cautious though. I also think having the base bin file that he uses, assuming he has no interest in selling them anymore, in the (relatively) public domain of PFF and other fiero resource sites would be invaluble. Maybe stickpony would be willing to share how the bin works. I would think that regardless of whether people know how most would still choose to have someone else do it, alot of that having to do with the buy in regarding a prom burner. Also I am going to have to agree that although the caddy diag system is built for the thing it just seems like it would be a huge hassle to get to work correctly in a fiero, not to mention it adds a fairly large amount of other stuff that you need to complete a swap. I actually considered going carbed to avoid all this hassle but decided that if I was going to do that then I would just do a 350 instead. Partly its the technology that makes the 4.9 so great and helps people achieve mpg numbers in the high twentys and low 30s definately one of the deciding factors when deciding on a swap to be used as a daily driver. Jscott where is your 02 located. Mine is on the rear manifold. I went heated because I didnt know where I was going to put it.

Let it be publicly known that any delivery issues i have had in the past was just two customers, and i made good by them. The "roadwarrior" job that I had that kept me away from home is no longer my job, i have found stable long term work in my own hometown, so i have plenty of free time on my hands. the turn around time for a chip burn is 5-7 business days, solid, i will guarantee that. and to show you what a good guy i am, i will reflash it to the specs that you provide me request for a discount, as well as give you the "superchips" tune if you wish it.

please email me direct at stickpony@gmail.com, or call me at 561-201-6191, and i'll get it done for you quickly..

Neither A8 or A9 worked?

yeah neither. When I have some time this week I will double check all the wires and make sure they trace correctly. I think I may actually try and redo the entire harness. I decided I wanted to route it differently to both avoid the heat issues I have been having and to make it more concealed. Rather than add new splices to everything I figure just do it over.

Did you ever get this thing to scan?

No. I cooked the bearings and decided to put in another engine rather than having the old one polished and rebuilt. I got it all built up on the cradle and then a bunch of things have continued to get in the way so it is still disassembled in the driveway. I decided to re wire it while I had the engine out this time with fiberglass sheethed good to like 1000 deg F wire. I am slow. If I ever get it up again You guys will be the first to know.

Dizzixx wanted let you know I have tested my AutoXray 5000 on my swap car. All worked as it is supposed to with communicating with the ECM. Mine is wired per Mickey_Moose's wiring instructions.

Joe

Cool deal thanks for letting me know man. I have finished most the wiring as well as taking care of the heat problems. Its back in the car and hopefully we will see if I did it right this time in the next week. Keep your fingers crossed.
