Im running hitmans map for 550/1600 with a To4 turbo

right now I have 550/1680 injectors. My problem is the car falls on its *** as soon as it hits boost.

Im sure this is from too much fuel. Most of the maps, when switching from stage one to two; It goes from around 7ms to around 3-3.5 ms.

Now, if im correct. that is a 200% increase at the changeover point.

I dont have a wideband yet, but I would like to at least get it boosting so I can get some other **** figured out.

anybody got 550/1600 maps that I can compare mine too?

 

I have one for 550/1600 with a GR-63 turbo. It's still rich in the boost zone. But I'm running ign/by 1 not 2. So our numbers will be off. If you want it let me know I'll e-mail it over.

Try one of these, see how they help.

Later,

 

none of those maps run anything higher than 850 on the secondary, and thats where my main problem is.

Ravens map is about generally about 2/3 of what my fuel maps are, and he has a Higher HP setup.

unfortunantly, my fuel pump is being rebuilt at aeromotive, and still got at least another week before i get it back. I have no way to test on the road.

 

Did you look at the entire post?

Here....

E6X map, 550/1600cc injectors, some mods, turbo upgrade.

As always, please go through all the settings and make sure they are right for your car, and ALWAYS ALWAYS ALWAYS check your timing and make sure its aligned right between the haltech and the engine.

 

sorry I have a E6k, should have mentioned that.

 

Yes, that would've been important....

Here.....

E6K map for Series 4/5 with 550/1600cc injectors and some mods.

 

Yeah my map would be around 2/3 if not less then yours. It you are running ign/by 2 you want a little less then double my bars.

i still dont know what you mean by that.

I have been looking through the manual, and I cant find any answers.

 

Here is a quote from a chain of e-mails on the yahoo Haltech forum going over ign/by 1 and 2. The final post is by Hitman as most know is one of the better haltech tuners.

__________________________________________________ _____
The rotary fires twice per engine revolution actually, but yes once per rotor. :-)

If you fire the injector once per crank revolution as we do with an IGN/BY of 2, what you end up with, technically, is sequential injection with rotor 2 being 180 degrees out of phase.
Firing the injectors twice per revolution means you have one pulse for each rotor on time and one pulse off time. Seeing as you cannot really adjust the time of the firing anyway on an E6K, the benefit of getting it on time is lost and then you need to deal with the pulse that was out of time. In effect you get drenched port walls and with it lower atomisation efficiency at low rpm.

If you get a chance to play with true sequential on a rotary you will most likely find that having the phasing of the injectors out by even a large margin does not effect the running of the motor all that much, and once off idle the difference is virtually nil. Sure there is a difference but it is nowhere near as much as for a piston motor.

The other benefit to using IGN/BY 2 is that the injection time is higher which give you a little finer control of mixture, and the bigger you go with injectors the more it matters.

In the end it does make any difference which one you use so long as everything is tuned right. After playing with it countless times on my own engines, I reverted to using (2) for all engines and have not had any problems so far.

This is one of the threads that has always got me confused. I hope we can continue
this with a few more replies...

It's well known that the rotary engine fires once every one "RPM"; this is strictly
talking about the ignition firing. Yes, if we pick a /1, the Haltech will fire one
fuel injector properly for one (front) rotor, but it was not fire at the right
moment for the other (rear) rotor. This is for a typical E6K (or equivalent)
application where running in "staged mode" can only mean the first (primary) fuel
injectors are firing in batch together.

If we pick /2, isn't the fuel puddling problem more of an issue since you're trying
to deliver fuel for every other (front) rotor face? If the Haltech were set to /2,
you'd have one (front) rotor face missing a fuel delivery "event" alternately? In
/2 maps, the maps are typically double the heights versus the /1 maps. In fact, we
can't properly deliver fuel to the other (rear) rotor since due to the sheer nature
of the firing order unless we can pick a ".5" setting?

Am I totally wrong somewhere?

thanks, that cleared everything up

I think might have had to do with my fuel pump going out. I didnt see a pressure drop on my FP guage, but who knows.


Im going to set my trim to FINE fuel control, and play with it a little. This winter, I will be pulling my motor, and have it professionally tuned on a engine dyno.

There are no chassis dynos in my area (except for monster Semi-truck ones) but a local performance place has a 1000hp engine dyno, and I have heard nothing but good things.


Claudio, those fuel maps are identical to the hitman ones that Im using now.

 

I've talked to matt a lot of times in the past, when i was starting out he helped me quite a bit, as well as tech me some very important haltech tuning tips, i have a few maps from him as well.

I also saw his way of making the maps as smoothly transitioned as possible makes for a better running engine. I guess you could say he is a mentor.
