haha, did I mention I'm a Freak on T/F "thumbs up" . I already looked at his site BUT, I still want to get more info ect. I have talked to him about it numours times, just well yea haha, thanks though

lol....NEWBIES My Merkur made 334 rwhp and 349 lb ft with only 18 psi from a stage 2 turbonetics turbo, and 2 supercoupe intercooler cores welded together..... 7 YEARS AGO, with a MAF conversion (yes vane meters do suck), and homemade MAF signal adjuster. If you think MAF sucks, you simply don't have a clue. A TD will never drive as well as an EEC IV.....

The dodge stuff is junky, the processors are slow, the adjustment points on the tables are limited. Speed density is nice, hence why the GM swap is the most common one, those guys are light years ahead of anyone else....visit some of the SYTY boards, and read.

Any adjustment is better then no adjustment, but if you are going through the trouble of a computer swap, do it right! The GM system has full 3d map versus rpm tables for fueling and timing, boost control by speed and boost by rpm, and with a little ingenuity (visit diy-efi.org) boost by gear. It also datalogs with no fancy boards or software (all freeware), and has put many SYTY and GN guys into the 8's and 9's.

The only software available to joe blow for TD's is CHEM....it works, but is very limited right now, or you can buy custom cals from some guy of the net. If you are serious, you need to learn how to tune yourself. ....unless you live next door to relentless

I would say that's rather biased and subjective.

On the other hand I have worked on Ford and GM systems in the field and the Ford sytems have always been the biggest PITA to work on.

The GM systems are rather good with lots of information.

Junky? How so? The processors are twice as fast as they need to be and I'd point out that Fords use fixed tables for fueling while Chryslers calculate the information on the fly.

Adjustment tables are limted? Need to explain that one, I have no trouble making all the adjustments needed.

I don't know about the later stuff but I have been trading notes with a few Gran Nat tuners and the Chrysler turbo stuff is way better then what they are using.

Dpending on the year the Chrysler systems have 3d fuel and spark mapping (which I point out a lot of popular aftermarket systems do NOT), boost control is adjustable by engine temp, speed, time, rpm, charge air, toggle with a switch AND thumbwheel adjustable.

Hook up an OTC scanner and run the cable out to a laptop, more information then you can shake a stick at AND viewable in a spreadsheet to boot.

Agreed on Chem plus even if you learn your way around the program it still doesn't tell you how things *work* or give you access to constants.

Learning how to tune is the biggest thing you need to know, your engine will give you information telling you what it needs and you would be surprised how few know how to interpret the information.

If he did live next door we could have fun tuning the car ;-)

Straying from the fold, Mr. Merkur? Instead of trying to fit Chrysler brains onto my SVO, I think I've decided to get rid of my beater '87 Mustang and get a turbo Daytona. Probably easier than doing a brain and nervous system transplant! Good luck, though."thumbs up

Bryan (aka SVO42, "Insane Poster" @ TurboFord )

there are a couple things that make my TF a little better than a TD. My Ford is rear wheel drive:big grin: , no torqe stear , I like my body design a little better, my Xr is a little different from about any car "thumbs up . I am NOT raggin on you guys or your cars, I really like them just that fwd thing. . .I like them, I appreciat them and its just like me and my T/F. I am just working on getting the best of both worlds

[SVO42]

I was just razzin' you a bit, man. A little "brand loyalty" humor, that's all. Talk to xrattiracer and nemiro at TF. Both of them have Mopar brains on their cars (Merk and SVO, respectively). Good luck!"thumbs up

I would like to do the conversion to, on my 87 Mustang 2.3 Turbo Now I have a ECM from a 89 Plymouth Sundance RS 2.5 Turbo. How good is this ECM for a computer conversion??? The injectors or 5277895. Do you have any Pic of wiring harness diagrams that you can send me??? Thanks for the help! Your help is Appreciated!!! LDSNOMD@AOL.COM "thumbs up

Neil Emiro got bored and did this already. Visit his website and it gives a brief outline.:big grin:

I know people have done this already and had great luck, I just wanna find were they had problems and what they could have done better ect. and do it better"thumbs up . I am debating on just not doing the swap for a long while and do something else, make my own go cart powered bye a small car engine"thumbs up . the hot rod lawnmower was cool but the wheelies arnt so fun anymore after being bucked off so much, time to have a fast tight handling honda eater:big grin: . I will just work on this swap as supplies permit, I have about everything figured out for it now. Thanks

How about a 65-70 mustang fastback (6cyl removed) with a ford 2.3 4cyl turbo with TD brain? Wonder if anyone has done this?
