box fuel injection

Maybe you already know but in case ... If you are in need of a new Thermo Time Switch for Bosch FI you probably know it is difficult to find the original Bosch # 0280130214 (OEM Fiat # 4393600). I found a PDF Bosch document specifically for the Thermo Time Switch. The Bosch F026T03100 it is...

Well, it's about time I spend some time behind the laptop updating you guys instead of in the garage. Originally I wanted to keep this project a secret, in the spirit of FFO being local this year and wanting to surprise my local chapter with my mischievous behavior. Sorry for lying to all of you...

Is there a definitive answer (I've looked but haven't been able to find - so if I missed it, kindly point it out) about which FI hose sizes are best? MWB no longer sells 7.5mm - "We have chosen to offer this product in 7.9mm (5/16") high pressure hose...and have removed 7.5mm high pressure...

Well, I may have just come across an issue that may be the root of some of the unexplainable high rpm running issues. The fuel injector harness- both the outer layer of insulation and the sheath on the copper wire itself, are rock solid and brittle. There are many locations where both the feed...

I got my 1981 Fiat X1/9 out of storage and found the Ex. Gas Sensor light was on all the time. It was telling me to replace the Lambda Sensor on the exhaust manifold. See pic1.jpg. In my 1981 fuel injected car, the sensor could be accessed easily by removing the cardboard cover and metal...

I want to replace the hose pieces that are red in this pic (stole the picture from an old Ben Louis post - thanks Ben!). I believe it is the auxiliary air hose part no 4446161, or maybe its a breather hose. Does anyone know the ID so maybe I can just go to Napa and get something off the...

Can someone please tell me what this means and how to check/ fix the problem? The Ex. Gas Sensor dashboard light came on yesterday as I was pulling into the garage. The car seems to idle and run normally.

A few years ago I had one of my OE cloth covered fuel lines from the pump to the filter burst, no surprise as it was well past its use by date. I had bought some 7.5mm fuel hose prior to this as it was my intent to replace them anyway so I was prepared for this eventuality. Happily this is a...

I've got some injectors I picked up some number of years ago that are labeled X1/9 and others that are labeled 124. The part numbers are different so I'm wondering if they injectors are car specific? The part numbers are: 4430293 (those are labeled X1/9) and 4393596 (those are labeled 124)...

I have a couple questions regarding the Aux Air Valve. Currently I can only start my car with the throttle fully open (accelerator down to the floor) and then have to give it gas for about 2mins before it finally idles on it's own. Even then it's a rough idle, idle clears up after a 10min drive...

I was just about ready to put the fuel rail back on my car when I noticed that all four of the o rings for the injectors seem to have vanished. Plenty of vendors sell the large and small seals as a kit but omit the o rings. The only one that does have them is Midwest...

Does anyone know if this particular CJ50 Cold Start Valve will work for an X1/9...

-A wiring instruction on how you add fuel injection control to what would formerly be a carb'd X19. This section covers the interface to the Fuel Injection harness only. This would be your starting point. If you have all the hardware from a Fuel-Injected X that you want to put into your...

Since this post has been stickied here is the link to the post that covers the hardware and also a link original thread this came from. http://xwebforums.org/showpost.php?p=99879&postcount=16 http://xwebforums.com/forum/index.php?threads/12955/ When I first began researching this project I...

I recently installed one of Matt's high performance heads on my 85 Bertone. When I posted this, Matt asked if I'd done any AFM re-mapping. According to him, many of his modded X's run lean, and need to have the AFM re-mapped. Reviewing the archives, I decided to try Matt's AFM air flap test...

Hey all, in my white '83 X, I have a newly rebuilt 1500 slightly modded with milled head (.070), adj. camwheel, PBS SX-1 cam and homemade header/exaust with open cone type air filter. It runs really good, better than I expected in fact. I got a spare AFM sitting around and was wondering if there...
