My son has an ’88 GT that is currently running long tube BBK headers and a Crane Compu cam 2030 and a speed density computer. We are adding GT-40p heads, and an Explorer intake. It ran great with the previous combo, is this likely to upset that very much? I’m guessing even if it still runs well, I would need to tune it to really get the most out of the combo. I’m thinking I probably need to go with 24lb injectors too. I’ve read DougH9 threads on his project, and that’s the sort of results I’m looking for. So Doug if you are out there I would appreciate your input. Also is a wideband gauge mandatory for this?

I tuned my Dad's 87 with the quarterhorse and BE. It turned out well. I had sailorbob create a definition for the speed density computer. It has a CompCams XE264-hr12, AFR165, Cobra Intake, and shorty headers. Prior to the tune it had a hunting idle and weak performance for the combination. Now the idle is stable and it runs well. It's my Dad's daily driver but has not been to the drag strip or dyno. After I got the Quarterhorse working, I added FRPP 47pph injectors and re-calibrated for them. It handled them fine and has been running great with this combination for the last three years. I don't see any downsides to the speed density computers for naturally aspirated applications and think you will be pleased with the results.

We finally got this car back together. We went to swap heads and found a broken piston in cylinder #7. That would explain the fouled plug and high oil consumption. We swapped in an Explorer short block I had along with the Explorer intake and GT-40P heads. We kept the Crane Compu cam 2030 and the long tube headers. I have also since acquired an A9P computer and tweecer. (Thanks mikej49). We have run it both with a speed density DE computer and the A9P. It actually seems to run better with the Speed Density which surprises me. I am ready to start tuning, but I'm not having much luck getting either BE/EA or TunerPro RT to connect to the Tweecer. I also tried to look at the templates in the Templates 101 thread but few of the linked files are still available. The links in the Getting Started thread also don't work. Are those still around somewhere?

no one that i know of has a publicly available plugin to use a tweecer with tunerpro, if you want free cheap you'll have to use caledit

you can't swap strats either so that means no a9l2 for you

Thanks, I didn't realize that. I spent some time on the tweecer support site and got it up an d running using caledit. It sounds like most here are using BE/EA. I'm not sure I want to spend the money yet to license it. What can be done with the unlicensed version? Also decipha, it appears you are the author of many of the templates in the templates 101 thread. Are those available somewhere for download? It looks like they were written for the GUFB, but will they work in GUF1? Thanks in advance.

[decipha]

no they aren't that im aware of, I kicked up the a9l2 tune which replaced all those templates

the problem with templates are that anything important like spark and what not would require the scaling functions to go along with it which would require the fueling to be adjusted which means scaling would have to be compensated for etc... it just keeps going on and on, for a noob its really not safe

best bet, a tune you can start from with known variables and go from there, hence the a9l2

you'll need a gufb ecu to use it though since you have a tweecer you can't swap strategies

Hello OHarris,
I just checked in after a bit of time off and saw this thread. My engine was not that hard to tune with quarter horse and BE. I also got the analyzer program (EA?) but never figured out how to use it. My car ran super rich at idle and part throttle idle with the stock tune. I got QH&BE hooked up (the hard part), and a definition from Sailorbob, and a wide band installed (as a stand-alone component). I just started with the stock tune and just started massaging the VE table until the wide band showed good numbers. That is 90% of the job. Later I swapped to 24 lb injectors and changed the tune for that, and then upped the timing table a bit. This was all easy. The hard part is getting set up and learning what to do. My car runs very good now-clean at idle and part throttle, super throttle response, and pulls like hell to high rpm (for a little 302). I like the SD set up, if for no other reason than looks (not having a MAF sensor and hoses).

I am still a noob and do not know this stuff that well, but I will try to help anyway I can.
