Ok, so my injectors have been acting a little funny lately. I considered just rebuilding them, but I decided I wanted to try something else instead. I know that the Disco 1 guys like to upgrade to the ford 19lb injectors and I decided I wanted to try something similar. I couldn't find any injector specs online, so I just called Bosch Automotive directly. I told them I had an 03 Land Rover Discovery and I wanted to upgrade injectors. They told me they would call me back soon. About 15 minutes later (I was amazed!) they called me back and said they couldn't tell me exactly what I needed, but that they would email me a ton of technical specs. I looked through them, found out what we had stock, and cross referenced to see what would work. I finally settled on a set of these. They are Bosch 24lb EV6 part number 0280155715 used in quite a large number of Ford vehicles. They are listed at $100 for the set, I made an offer of $75 and they accepted immediately. Personally, I think they would've taken at least $5-$10 less, maybe more than that. Anywho, I am almost positive they will work, but I'm not sure if they will make any actual improvements at least without a tune. They should be delivered to me some time between the 28th this month and the second of December. Once I get them in I'll update and then I'll update after a couple tanks of gas.

I believe you will need to tune the ECU to adapt to the increased amount of fuel being added. But, I'm not certain if the ECU gives the commands straight up or if the MAF sensor gives the commands. Right, aren't some fuel duty cycle programs written based off MAF values? And some cycle off was is written to the ECU?

Completely different application, but I ran larger, 440cc, injectors in my Audi, but had to tune the car to adapt to the larger volume of fuel being added. Twin turbo 6cyl, car was a Beast.

 

Yea, I've got my first gets crossed that I won't have to since the Disco 2 guys don't. Hopefully it will adapt a little on its own based on O2 data after a couple tanks. If not I'll have to either clean out the factory ones and switch back or figure out some way to get a tune. A tune woukd be awesome with cam and larger injectors, could really bring it to life.

 

Anyone know us there is some kind of software I can get to do a tune? Can any of the expensive code readers do it? What about that one (can't remember the name) that you use in your laptop, seems to be a cost effective way to get ABS codes?

Also, Happy Thanksgiving!

 

You could use the Lynx Diagnostic System: Lynx Diagnostic Tool For A Single Rover Vehicle

This one does just about everything.

 

Whew, that fella is expensive. Not really suprising, but still a lot of moolah.

Edit: Just called AB. The Lynx scanner will not modify fuel maps.
