cobra computer

For the money and hassle, you'd be better off buying a tweecer R/T and just loading in a straight J4J1 (Cobra) tune.

You'd then be able to make some performance changes ontop of the Cobra tune to make it match your combo exactly as well as pull out some of the performance killing settings (shift retard etc).

how would you go about doing that i mean i got the R/T and #24 injectors?

i have heard of peeople doing this but they never said how.

If it all seems kinda over whelming ... I know how you feel :)

See if this makes sense about other self tuners point of view :shrug:

I think it is unreasonable to expect folks to be specific about self tuning because ......

To give a step by step process is VERY involved and there are MANY additional little things that help make the main objective go smoothly which also needs to be included with the main info.

Several years ago I tried to give specific details, provide charts, and share data from my findings of Tweecer self tuning. I think a few peeps liked the data and hopefully some benefitted ......

but for the most part .............

I almost went crazy trying to help peeps here and on other sites. I got very frustrated and finally had to let my pm's fill up to stop the request of help for info that was easily found at many sources.

I realized I kept answering the same Q's over & over & over :bang:

I finally had to take and put into practice the attitude of ......

Nobody spoon-fed me self tuning info :nono: yet I learned it :)
Why should I spoon-feed others!

I now give general info only or point peeps in the correct direction so they can find the data to understand what they are trying to accomplish.

Kinda like ...... I don't hand out fish anymore :nono:
I give a few general tips
and
give them a map to Bass Pro Shop
which then
allows them to teach themslves to learn how to fish :D

Just said all that so you can see how you have to invest a bit of time to pick up the basic stuff ... after that ... the info you find at various places on the net all makes sense :nice:

IMHO, I think it would benefit you to lurk around on the Tweecer site and get a bit of basic understanding about the Tweecer self tuning thing.

Honestly ... without that ... the Tweecer is almost useless and ......
About the only kinda thing you end up using the Tweecer for is:
idel speed
egr toggle
global spark
and other simple tweecs

I've given a good bit of basic or general info here and on Corral and there is some basic stuff on my site that might help. If you search back like two years or more you will be able to find more specific info ... if its still around.

The self tuning community from my view point ... I guess :D

anyway ........

The basic jest of this Q is you can put the programming of the Cobra pcm in a GT pcm because it is of the same pcm family. If you are still using the stock maf, you would need to switch to the 24's at the same time you switch cal files.

thanks guys that sound intresting, im going to do some research on the tweecer R/T and ill let you guys know how it works out. the reson i was asking about the cobra comp was because a friend was selling one and i thought it might work out since i have on my stang the following mods bbk cold air intake, bbk 70mm throttle body, bbk pullys, bbk shorty headers, bbk x pipe no cats, msd blaster tfi coil,stage one spec clutch and 390 gears. :nice:
 
Where the j4j1 shines over the t4m0 is when you get to the point with your combo where you have gone to aftermarket maf/larger inj's.

J4j1 really does work well for a platform to build upon from that point on.

If you only got little stuff like pulleys, gears, rr's and the like, the t4m0 will usually yield a bit more power than the j4j1.

I've seen many say they lost power when switching over to the j4j1 but that is easily dealt with by doing a little spark tweec here and there.

Really depends upon what your long term plans are. Just to switch pcm's and not be able to optimize the switch ... Don't think I'd do it.

Hope that gives you some ideas :D

your right i was going to upgrade my maf/inj's along with the j4j1 since my friend is selling it for 25 dollers for my next mod, i just didnt know if the j4j1 would be compatible on a 95 gt:hail2:

just wounder if any off you guys have installed a 95 cobra computer along with the 24lbs injectors on a 95 mustang gt and if its a good mod to perform thanks:shrug:

Check out the sticky in the tuner section here. Also, go on Corral and search under "Tweecer". There's a thread there that is pretty long and dated, which should provide some needed info.

i forgot to add that i have a Trick Flow intake manifold as well:bang:

I think I've kinda pieced together your combo now.

btw ... a sig would be helpful for members to be more effective at answering your future Q's.

You could move to the Cobra pcm and 24's and the switch most likely would be non eventfull ... but ... I would tell you to keep the stock maf.

You really would not benefit from a maf upgrade at this time. That maf will pass a lot of flow and certainly be able to more than deal with your currnet combo status. If you gained anything, it would be very small and the possible drivability issues from the switch just would not be worth it, IMHO.
