94gtcoupe

Hey, i'm new to this forum.. i have a 94 gt coupe little done here and there. but i'm frustrated with obd1's untunable ****. i was going to put and obd2 in it and start from scratch tunning it. my question is what all do i need to do the swap and how do i go about doing this. i know the computer is a direct plug in since ford was getting ready to switch to the obd2 with this body style.

to make it easier get a twEECer or PMS unit and have someone tune it for you. you'll get a lot more out of it vs. just changing to a new style computer that still wont recognize your mods...especially thenew cam

Changing a '94-'95 SN95 to OBD-II is not a plug and play deal. You'll have to make a lot of changes, addition of sensors, wiring, etc....It would be more effective (and cost effective) to install a Tweecer or PMS as 50mikey mentioned....no rewiring required....

how much does that cost? and i'm able to tune it myself as long as a obd1 or obd2 scanner can do it...

Here you go....check both alternatives out....

BTW...a Tweecer R/T is what we're using on a '95 GT S/C w/42# injectors, etc, etc I'm working on....works great.

a PMS is way more than i'm looking to spend, the tweecer is a little more resonable in price, but does it hook to a computer so i can review what the engine was doing when i make a run, and can i havea friend in the car tunning it on the fly when i'm going down the road?

It is best not to tune 'on the fly' as the car can stumble or even die when a new tune is loaded to the tweecer module.

The tweecer module has 5 positions, 4 can be tuned, and 1 allows the use of the stock tune.

Don't bother with the base version, the TwEECer RT will allow you to datalog. Trying to watch your sensors while running will be over whelming and un-reliable.
Spring for the RT, you won't regret it.

As with Joel, I love the tweecer. For the price, it allows a great deal of flexibility.

i wasn't saying that i wanted to watch the tunner while i was running i want to watch it after the run, i guess i should reword my question... does the tweecer rt store and of the data log

if i get a h/c/i set up with a 70mm tb.. 73mm maf... 24 lb inj..... 255lph fp... fpr...full exhuast and other bolt ons would it be worth it to get the tweecer rt?
