can these be ran on stock ecu?

 

You can control the IPW down to whatever you command and you can also use the non linear pulse width compensation table. Whether or not it runs well is a different story because you will have a minimum IPW and that value may force you to run very rich at idle.

 

If you truly need that much injector (over 1000whp) you should absolutely be running a standalone EMS.

 

i would be curious if the stock ecu will control them.

tuff to get stand alone to pass emissions

 

Its a 20 year old stock ecu with no fail safe protection with some hacked software. If you need enough injector to make over 700+hp a standalone is a great investment.

Tough to change the engine after a few runs also. Stock ecu has its place, just not on a big power car .

 

yea... tru.. i would agree....

however, i would still be interested if the "hacked 20 year old ecu": would control them.

 

While I do agree a standalone should definitely be considered, although not a necessity for a street evo.
I have been running mine for 5+ years on stock ecu, 2150cc and big power. Not as smooth as I'd like but it works.

 

We all have a comfort level.

Big power with out any fail safe protection is out of my comfort zone. Your investment can burn up in seconds. We live in a world with so much technology, why would you want to count on something outdated?

Do you prefer a nokia from 2002 or the latest smart phone? LOL

 

I think with the stock ecu there are going to be a lot of gotchas that would need to be dealt with. A standalone would probably take a huge chunk out of the dev process to getting these things driving well. These will be so sensitive that the way the stock ecu does just random stuff like pull a little fuel to test sensors and what not would have very magnified effects. This is true of all bigger injectors and good tuners know how to deal with it. I think these would just be jumping up to that next level where you really have to get in there and reconfigure how the stock ecu operates. Perhaps to the point where you need to modify firmware to get more resolution, bigger tables, etc...

 

The problem with larger injectors is that a very small change in IPW has a significant change in fueling. This issue is more pronounced during idle and low load cruise because you will need the ability to make very small changes to the IPW to get the desired fueling. It is not that the stock ECU cannot control such large injectors, but if your IPW control increments are too large then it might be difficult to get the setup to run smooth.

 

I am not denying the advantages of using a standalone compared to the stock ECU. I am just very comfortable tuning the stock ecu myself and have not found it absolutely necessary to change to an aftermarket yet. A Standalone has been on my list of upgrades for a long time, more specifically a Haltech 1500. But my current setup has been so reliable I just don't want to mess with it.

 

It's not like the stock ECU doesn't have safety measures, it has plenty and tephra adds even more. It's up to the tuner to make sure they are all configured correctly and not just turned off.

 

Have you used a standalone ? I’m going to guess you haven’t. Life gets much easier . I understand you feel comfortable with the stock Ecu. It’s got it’s place but not on a high powered car imo. Stock ecu is playing with fire at big power.


Will the stock ecu cut if it goes lean in a gear?
Will it cut if you lose oil pressure ?

Some stand alone features.
Set a target afr
Live adjustments
Shift cut for a strain gauge.
Data logging without pc.
Faster data log
More logging channels
sequential ignition for better knock control.
Control fuel or ignition for each cylinder.
etc.

 

Yes I have a F.A.S.T. for my mustang. It's very limited by today's standards, but it does the job. It doesn't sound like you're fully up to speed with what the stock ecu can do. I would never claim it's the "be all end all", but it's more capable than I think is being represented here. I don't want to get into the weeds and start arguing point by point or anything, so I'll just leave it at that.

The mac is a little dated though, our ECU is more related to this:

 

wait a minute... we can play video games on our ecu?




its a joke...before people go nuts
