General FIC 2150cc on EPROM?

[kchaazz]

Hey, Ive been looking and havent been successful in finding an answer to this one, probably because noone's tried it yet as these are still relatively new and not many people need injectors this size. Im looking to convert to E85 soon, and I might as well just buy the biggest injectors I can get my hands on because Im not sure how far I want to take the car yet. As the title states, has anyone tried dialing in the FIC 2150cc injectors with an EPROM chip? With or without an Easytune box? From what Ive gathered so far, these are high impedance injectors and utilize a saturated signal, requiring the elimination of the resistor pack, which is a relatively painless procedure, and these are also supposed to be a lot easier to dial in. If noone can answer, thats fine and Ill be the "tester" and will just post my results and if it doesnt work, Ill just buy DSMlink

Also, if anyone has DSMlink and these injectors and wouldnt mind swapping in an ordinary EPROM chip for a few minutes, I could burn you a chip mirroring your global and deadtime settings and ship it to you to try out. (I wouldnt expect you to run your car with my chip. Just see if the car idles well and if the wideband and low fuel trim is close to being in line

If it can be done with link, why wouldn't it be able to be done with a custom burned chip? You change global and deadtime in both, correct? if so, what type of info are you looking for?

And from what I read, people using link and 2150's aren't using the EasyTune box.

Agreed no easytune box here, but chip might be asking a bit much IMHO. You could probably get them to work but they aren't the easiest to get dialed in on pump.

Yeah that's what I was getting at. Link has a few more features to it that you just don't get with an EPROM, like a fuel slider to play with.

I think it could be done perhaps by getting the deadtime and global close and then tweaking the cells in the fuel map in the idle area, which would be a lot quicker and easier using an Ostrich in realtime, which my roommate has and would lend to me. And was also thinking in the case of an EPROM that the Easytune would further simplify things by sending a constant, static voltage to the injectors, thereby requiring the modification of only ONE deadtime cell .

I was kinda hoping someone had tried this already but its ok, I'll figure it out and get back to you guys if I can come up with something helpful to the EPROM crowd.

Yup no easytune is needed. 2150cc injectors allows my talon to start and idle better than the 1750cc injectors that kind of required the easytune box.

This was with dsmlink v3

V3 ECMlink maybe has a few more features... But DSMlink you have less control IMO then with a custom chip as there is no direct way to change the Timing or fuel maps along with no way to change the Deadtimes per voltage like in DA in V3... .

Any way... .

I Don't see it being a problem I can and have run my BM 1450's with out a issues Running SD on a Custom Eprom Chip with out a problem.

2150's are high ohm and have real low deadtimes there as said no reason for a Easytune and anyone that knows what they are doing should be able to use them that way with out a problem

^ A year late there buddy

Wups didn't see the year

Just to get the info out there......

It can be done. You'll need an adjustable fuel pressure regulator, unless you re-write the ecu code for injector scaling. With that large of an injector, the stock code can't get the exact injector size, as the way the formula is written, there are 100cc and larger gaps in the available sizes.

Fine tuning the scaling has to be done with pressure, which is also very sensitive to changes. A small percentage change to a smaller injector isn't a big deal, and can be trimmed out. A small percentage change to a 2000+ cc injector is a large difference.
