Hello
I have a 90 GTA with a warmed up 350 TPI motor.
i programmed the new chip etc, i.e. i have all the above mentioned stuff and would be glad to help.
now the bad news.
its ben a long time since i used this stuff, i will have to relearn. it uses an old DOS laptop.. but it all still works.
and u will need to come to my place as u can not do this "over the phone"
i also have a WB 02 setup. sooooo
let me know whats up.
i live near Silverdale.
Mike

You'll need the car to tune it. No way to do it right going by specs. I think there's more you'll need as well, but never done it myself. Several people here have done their own tuning though, i'm sure they'll let you know. I think Mangus even wrote the software you'll be using.

hmmm well i doubt i can get my car up to silverdale haha, i thought you just plugged the prom into the computer and adjust things, do you have to do it while the car is on or something?

Depends on the setup you use. I ran Moates Burn1 and ZIF socket chips, so chip burning could be done remotely. You need to datalog the car in various situations, then go back and rework the chip as needed. No way it can just be done in an afternoon.

Let me put it to you this way: I started burning chips for my IROC in Spring of '08 (IIRC) and when I sold the car last July I was still fiddling with the tune on it.

the reason i need ur car is to plug in the computer and see if all sensors etc. are working and also to log actual running conditions,.

i think u can burn a chip in a few hours that will get u close enough to run car as a daily driver ..

that said , can u please provide specific details about ur engine set up.
what ecm ?? current chip if u know. weight of car, cam, compression, tpi upgrades?? injector size, TB size, porting?? type of heads, headers??

does the car run?? i am about 30 miles from u all highway.

let me know info and we will go from there.
Mike

IIRC, he now has a TPI setup. He'll need an adapter to piggyback the new (modified) chip with the stock chip - maybe something like this

http://www.moates.net/product_info.php?cPath=64&products_id=32

If need be, I've got the Burn-1 and software from Moates, I'll let you borrow it. It's Windows based instead of DOS, but if you need to re-learn...

I'm going to pull the trigger in a couple of weeks and get RBob's EBL Flash unit and won't need the Burn-1 afterward.

Is he running the 730 ecm, if so i think the memcal has the EPROM in a socket, and i have several E&EEProm . yes its much easier to use a Moates zif adapter, i have one.....

Al would like to get together some time, i am now retired and was ET1(SS)... fun times, back then i went for lunch on base to the strip bar and we .......... u get it... Smile

i would be interested in ur burner...
anyway. we need to get that 91SS running,

later

its a good thing i bought a few extra 29C256....i also have a few original eproms
if 91RS comes over so i can look at his car, U are welcome to join the fun..
i live near the fairgrounds outside silverdale..more to come on this..
do u know what he has in his motor? trying to find a suitable BIN to start with.

You'll need a MAP 305 .bin for an auto car.

He's running a carb cam in the engine, so you'll have your work cut out for you.

*Edit: I believe this is the cam, you'll have to get confirmation from Luke on that though:

well as long as its TPI and a 730 ECM then a few tweaks to a 350BIN and u have a 305....if i have the car and can datalog all the better.
like i said it will be a learning experance for all..

my car runs but will not drive, so only way to get it to your place would be to have it towed...

and yes aaron that is the cam that i have

would the knock sensor have anything to do with the timing issues?? cause i am currently using the knock sensor that was in the block already from 1985....would a new one fix that? 2 days ago it threw two codes the ESC code and the knock sensor code

is there a way were we could remotley tune it to get it driveable and then i could drive it to your house and have it tuned with the car

aaron_sK · Posted: Sun May 30, 2010 6:39 pm Post subject:

Knock sensors rarely go bad, and are somewhat expensive. Wipe codes and see if it can be recreated. If it's throwing an EST code, then you probably haven't wiped since you last set the timing. Razz

Yes a bad Knock sensor would make car updrivable...
there are 2 sensors 1 for a 305 and 1 for a 350, make sure u have the correct one.
in order to do anything with the chip u must have the engine in good machanical shape and have all the coorect sensors working properly--then u have a chance to tune.....
do u have a 730 ECM?
