hey i just bought a 89 5.0 tbi camaro and i was wondering if the 30 dollar chip from tbichips.com is any good and what diffrence in et time it will improve?

 

His work is lame, that's my opinion. You can do better yourself with a little coaching from members on this site. The source of information comes from members on the www.diy-efi.org list but there are a BUNCH of them that post here and will give you the best bang for the buck.
The software is free, all you need is a computer (which you obviously have) and an eprom programmer aka "burner" which will cost you anywhere from $75 to $140. I personally like the $140 pocket programmer 2, it's dumby proof. I'll walk you through how to do your own burns. Think of it this way, if you DON'T enjoy burning your own eproms then you can sell your programmer for almost what you paid for it and still have an eprom you made yourself that'll out perform anything you can buy over the counter or mail order. Just some food for thought.

 

were can i buy one of thoose burner if you can tell me somewhere i can do it?

 

i wouldnt call his work lame, anyone that give yu money back if you arent satisfied with the product, is doing something right. he will write and re-write chips for you for free if you run the aldl and get ALL the specs to him.

If you plan on just reprogramming your own eprom you'll need an eraser since it is an eprom and not an eeprom. eproms require the UV light to erase the data before reprogramming. I'd just as well go with Craig Moate's flash prom adaptor. It's $70 or something like that and it lets you burn on 8 different calibrations which you can select from on the fly/drive. If that isn't cool I don't know what is. Since it's a flash prom you don't need an eraser, you just program over. Obviously it costs more money to do it yourself but it's the only way to get it right or to even know if things are getting better or worse. Winaldl data will tell you a general idea but the refresh rate is so slow that it's just good for checking a few things. Even the knock counts aren't where they really are occuring!!! This is why I can say that mail order eproms are lame. Do what you want, I'm just saying it's a waste of money. Just like spending $$$ on a 4 banger import when there is better bang for the buck in a car with potential. Oh yeah, and by doing it yourself you can feel the results, hands on is the only way to tune.

 

so uh, how do you tune it and know wtf you are doing if it only tells you a few things?? heh....contradicition

 

Experience. Results. Doing your homework. What's so confusing? Winaldl tells you your sensor read outs but they aren't a screen capture of a specific period of time. It's refresh rate is around 0.8fps. In the time it takes for the screen to refresh you could change a LOT of engine speed. You can still get a ballpark figure but only time will produce the best results, no shortcuts, sorry. Although if you had a wideband o2 sensor you could cut the development time in half if not less.

 

were can i just but a chip for my car so that i wont have to buy a burner or you guys burn me a chip and i will pay you

 

its not that easy, to get a chip configuration that is dead on for a specific engine takes alot of work, trust me i am just now getting into it, and there is alot of work on the spark and fuel tables to even get a stock engine to be dead on. no one without driving time and time spent delving into the datalogs, over and over and over and over, is going to be able to accuratly burn you a chip.

 

okay so i send an email to tbichips.com and he said for 40 he will burn me the chip for the exact parts my for car and the 350 injectors

 

It sounds like you have a totally stock 305 TBI engine (correct me if I'm wrong); why do you want to go with 350 injectors?

 

okay but im giving my engine alot more power so i have to get bigger injectors

 

what exactly are you doing to it to get "alot more power" and how much power are you talking about?

 

lt1 cam and heads,edelbrock lt1 manifold ,headers and mufflers,holley tbi adapter,350 injectors and custom chip thas all oh yeah and 3.42 gears posi.thats all im going to do what u think i will ran in the quater mile i was told mid 13's?

 

well i have had my tbi chip from tbichips for about 6 months with no problems... he also takes off the governor so i ran it up late one night and passed 110 by a good bit not saying any more though... but he does a good job and will tell you himself that you need the winaldl info to burn a better chip. i thought my chip was freid so he told me to send it back and he would check it and reburn it. i found out my ground wires came loos from the back of the passengerside head and that is why it would not run...

 

is there a fast update option avaiable for these chips to work with win aldl?

i used to have a buick regal grand national. with the use of a scanmaster you could get just over 3 frames of info a second
vs the stock like 1.5 frames.

or you could go with direct scan and piggy back the puter and get 16 frames a second.
