I found this article in the June 2000 issue of Hot Rod magazine. ITs a great article for anybody who wishes to learn more about their Tuned Port Injection....including tuning, how the ecm uses the sensors...etc etc. I put it on my Yahoo briefcase because on here it says its too big....so try it and see if it works...thanks and enjoy...
KYL98,
Thanks dude for the link to the good info! Mucho appreciated! I'm right in the middle of a 355 TPI build. I'm in Louisville, where in Northern KY do you live?
Chris
Thanks for the replies....Im in Florence KY....about 10miles south of Cincinnati ohio. Im actually getting ready to move to Lexington though. Are there any good machine shops down that way?? Hopefully Ill have my 383 in by winter anyway...lol
to anyone else looking for more info, i found a great book. its called TPI Swappers Guide. It has a maintance break down of error codes along with tons of other great info. You can get it on amazon for like 15 I think. I payed near 20 for it at barns.

i thougt about downloadeding this after much trial and error and printing it out. did that sound ok?
anyway, i understand that this is how you would do it for those who are interested.
save the info on you computer and then use a program for printing pictures out. start the program...something like 'picture it' and then call up the file and you should be able to print it out.
i understand it must be a picture program, word or any of the others should cut off part of the material. only a program to print out picutres will work.
just be sure to remind everyone that you are just thinking about doing it.
I thought they were 22lbs also....but it sure does say that. Must be a typo. When you look into the L98 .bin it shows 22lb for a injector flow rate......hmmm

Yes it will work, but don't forget that your L03 heads and cam are just as much of a problem as the TBI if not more so. Don't expect a big difference unless you change them too.
Thanks for the article link and the book link guys. It's much appreciated.
Yeah, I gotta post a big 'ol "thank you" too; Now I gotta rummage through the archives and find that issue! Exactly a year after that issue I got my Camaro, holy CRAP that would've been handy 2 years ago
i started reading that write up when i realized i have the same magazine at home and have already read it 30 times, lol very good write up and very informative. I came across that magazine at a library and the librarian just gave it too me.
Nice article! I'll have to go to the dyno to set my fuel pressure right.

Hey, i have that same article in my car magazine archives at my house. In that article it described the process of removing one of the screens on the m.a.f. sensor. I was wondering on ya'lls idea of which one to discard???
Since I just recently bought a 87 Z28 with TPI I'd be interested in reading this article.. But it seems the link doesn't work.. Anyone got a fresh one hosted?
I’m assuming that this is the article that you guys are looking for? I took the original that was floating around, straigthened out the pages, enhanced them so they were a little easier to read and put them in a single zip file.
I’ll leave it up for a while if that’s it.

I am thinking about buying that TPI swappers book, but I haven't seen anything but bad reviews about how the book offers no information on swapping a system, and that it only talks about how the system works.
Hey, guy's and gal's, there's also a book called Camaro Perfromance handbook, its for all 82-92 camaro's, it tells you all the quick and easy modifications for everything, even goes through the years from the pace car to the 25th ann. book give's all GM part numbers and aftermarket numbers along with the mailing address for the company's. thats how i found the GM ZZ3 cam. check it out, it was written by David Shelby
Great artical. Great information for the beginners like me. I just purchased a 87' IROC-Z from a guy that did $20k under the hood and just lost interest in the car. Car never has seen snow/salt in it's life and it shows. I will post some pics to see what you guys think soon.....
