jamison67 · 02-21-2010, 04:01 PM

alrite guys i am now replaceing the injectores for my turbo set up,,,,so i went on ebay and typed 24 lbs injectors,,,and 3 kinds came up ,,,,,,there were the ford racing 24lbs(not bosch manufacter but will fit still),,,and there was ford 24lbs racing bosch design 2 and design 3,,,,,,

i guess what im asking is what one will work best wit my application(im running stock 173 ecu)????? and another question is whats the difference between them all,,,,and most of all whats the difference betwwen a design 2 injector and a design 3 injecter?????? will they work the same

thanks guys ur thoughts will be great

I think the only difference is the spray pattern. The ford racing ones are good and have been used by others with no problems. Id go with 30lb injectors however since its about the most motronic can handle.

i thought of going twit the 30lbs ,,,but my only concern was will it start up ok and not be chugging to barly stay started,,,cause its receiving to much fuel,,,,,,

so what r my options on tuning this car ,,,i got a wideband from innovative ,,,,,and a chip copy of tcd,,,,the only way i now about tuning this car is messing around wit the rrfpr and the afm til i can receive the proper a/f ratio if i can even get it proper due to limited ways of working wit montronic,,,,,if there r other ways for me to so say getto tune this car please help me out cause i think on start up im going to need it

thanks

A "copied" chip? Nice.
(please note sarcasm)

I'd suggest a megasquirt, frankly. It's THE best thing you can do for this kind've stuff. It's relatively cheap to implement, it's OpenSource (so you can copy to your hearts content

), and it's really quite flexible. Tuning IS time consuming, but there are so many tunes out there, you'll probably find an existing one that is "very close".

well i had a buddy just call me ,,,he has a 97 m3 that he turbocharged,,,but is now upgrading it to run more boost so he is getting rid of his old injecters which r 36 lbs,,,,,he was going to just give them to me,,,,will the computer be able to handle these injectoers,,,,,and do u guys think that its a good idea for me to try them,,,,would the work if i had a lower fuel pressure rate

e30_kid89 · 02-22-2010, 09:29 PM

I'm not sure if it can handle 36lb. I *think* somebody was running 42lbs on the stock computer but later threw it out for MS.

As far as options go for tuning, you just listed em

You got a copy of the TCD chip I developed for TCD that he wanted to pay me peanuts for? That chip only has timing mods. You need a custom tuned chip to handle the fuel also.
