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...

TPI tuning article....

 

SWEEEEET! that is awesome... I might call HR and ask if they can send me the issue.

 

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

 

Is there anyway to make this a sticky for people? ??????

 

KYL98.....great post my friend. i have a new engine in my 91 z conv and i am missing about 30 hp. i will utilize this aritcle to help me find it.

thank again!!

 

Great post! I'm going to have to try this. Thanks.

 

Glad you guys like it. It REALLY helped me to understand exactly how the TPI system works......

 

Thanks KYL98, great article.

 

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.

 

Thanks BigAl. I just ordered the book, $13 and some change.

 

I got that book ...tis a good one ......tells the seceret of the 640 ohm resistor

 

boy i hope i dont get nailed but........

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.

ya'll have fun ya heeya!

 

the article mentions stock L98 injectors at 24 lbs. i thought it was 22??

 

What page is that on? They are 22 lbs

 

page 7, top right hand side

 

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

 

im purchasing a complete tpi kit for my 305 L03 V8. It came off a 87 Camaro that has a 305 LB9 V8 , will it work?

p.s. hey thanks for that link! awsome article

 

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.

 

so where can I get the cams and heads?

 

Sweeeeeet! Thanx!

BTW, what's the casting number for the junk 305 heads? How abou the high output (TPI ) heads?

 

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.

 

Off the chain article...:lala:

 

Nice article! I'll have to go to the dyno to set my fuel pressure right.

 

Thanks for the article! I'll try to D/L it later when I have more time.

Axe

 

nice article, couldn't get page 6 or7 to load however

 

nice article! Good find

 

nice article. i might see if i can get that issue somewhere

 

Very nice... as soon as it warms up, looks like I'm going to try some of those procedures. Thanks.

 

Kudos ... my brain hurts. Will probably have to read it a few times, but very good stuff!

 

should be a good read, thanks

 

With the crash of Third gen.org the link to the article is damaged, anyway to set it back up, love to read it!!!! Thanks

 

What page?

 

huh? I just clicked on a couple of the links on the first page and they worked

 

Sorry Guys!! The night I tried it was not working, got that cannot find page error. Thought I was something lost in the crash!! Thanks for ya'lls help anyway!!

 

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???

 

I was only able to open the first four pages, I must have the whole thing. I will try tomorrow and if I cant get it I will be looking for help.

 

maybe its just me but pages 4-7 didnt work.

 

All I get is a blank page, browser indicates done. Darn.

 

keep going back and use both links finally got it all

 

the link looks like it died. and damn i need to learn how to get some HP out of this TPI.

 

If any one needs them I'll host the article on my server for a while.

"right click, save as" they are packed in a WinRAR format to save space.

TPI Shootout

 

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?

Thanks

 

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

 

thanks for the link 83 crossfire TA, good article....

 

good article - what i could read of it- for some reason it wouldnt let me open pages 6 and 7.

I feel like ive learned something now..- unlike all those years of school

 

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.....
