How high is your fuel mapping table programed for?

Do you have a rev limiter set, at what point?

Does it run strong up to that "Soft" limit right now, or does it seem the engine is not making enough power to rev itself to 10K RPM?

 

I guess is not a myth anymore.

You are one of them

 

3oz in 5 gallons is not enough without the OMP, try that in a gallon with some decent race premix and you're nearer the mark

 

Perhaps you can define: "Can't rev up past like 4 to 6k"?

Is it hitting a hard line like a lowered rev limiter? Is it simply not getting spark or fuel that high? Is it just not able to because of going excessively rich or lean?

For example, limp mode is more like a lowered rev limiter. Unplugging the MAF makes the engine try to flood out it's dumping so much fuel through and keeps it from reving beyond about 3k.

 

talk with Eric Meyer before you delete the OMP. The findings that he shared with the forum suggested that you will get accelerated side seal wear with power lost if you delete it. Eric said it didnt matter how much you pre mixed--the omp needed to stay on the engine.
I really dont understand the value of removing it?

 

Well it's all Tunning right now, I got it to rev up much higher than 4 by leaning out the fuel maps and VE tables a little.. So it was excessively rich and wouldn't rev up lol... My OMP has lost power thru the elimination of wiring to the stock ecu and right now Im leaning towards completely removing the stock ecu and being fully stand alone with Haltech.


Has ANYONE tried the gravity fed reservoir idea sitting higher than the oil Squirters ? Will there be pressure from the motor sucking in the oil or pushing it up ? ---Disconnecting the clear oil lines from the OMP and rising them above into a reservoir somehow is what I had in mind...

I read that long thread about the importance on the OMP and how it lubricates the side seals, I know and trust me guys I would like to keep this thing working somehow.
I mean that is the evolution of the Rotaries now havin 3 squirters... But how about the RX7's running lots of boost with ONLY one squirter... Hmm.. And PhillipM saying he does not run his, maybe a Renesis CAN live without an OMP...... Hmmmmm

 

Talk to Eric Meyer.

Seriously.

 

Does he have an email address, why doesn't he shine some light on this topic..

 

He doesn't frequent the board. He occasionally drops by, offers tons of valuable information, then gets irritated at how it is handled and received in various ways by various people, and drops off for a period of time again.

So he probably hasn't seen the thread.

Go to the top of the page, click member list, search for his name, "EricMeyer", then either send him a PM or use the email feature to send him an email.

 

How do you have the Haltech wired? Which unit? Throttle? The OMP is an actual pump...so it really doesn't matter where the oil comes from as long as the pickup is full since oil ia a basically non-compressible liquid

 

So can I just give a switched 12v power to the OMP and be all good? I have a Haltech Sprint RE wired how it should be and using a throttle cable TB.

 

Talk to Scott again...the pump needs tp be hooked out to an output that allows correct stepper signal to the pump

Not a simple 12v connection by far

 

see attached

 

Sooo according to that attached file, the OMP is not even needed to really feed the rotor housings with the stock oil squirters and clear lines, as long as there is fluid dropping down them.. right > ?

 

Where did you interpret that

The motor pumps the oil through the nozzles......controlled by the signal from the PCM

 

fixed

 

I dunno... But there's gotta be another way to get that pump working or just to get oil to come out from the squirters other than the Adapter plate which still utilizes the OMP...

 

yes, choose an aftermarket ECU that can operate it properly

 

The Sprint RE won't run the MOP as far as I can tell....Scott had told me a couple of years ago they had figured out how to get it to run on a 2000...but it wouldn't work well enough to keep the stock PCM happy .....


You sure your injector staging isn't your problem? When I was running the Haltech on mine it was a PIA to get it to run in the secondary transition when the injectors all came online

Also check the ignition setup and timing.....they didn't read the stock trigger when I did it and it caused me a bit of grief also....

 

Well I snagged this sprint RE off Ebgay for $840 brand new, I doubt I will ever get a better model since they are more than $1500 or 2 grand! This one has to be good enough to work on an 8 since it was made for it and the 7's..
The Staging could be tuned better yes and timing settings are set to what the 8 requires.. That still doesn't resolve the issue I have at hand.. Squirters..
And yeah I might have jumped into conclusions and went in tough directions with this project I'm doing but theres gota be a way to get around this OMP with the stock ECU thing.. I really appreciate all the helpful input from everybody, so far ya'll been real helpful and not haters like other Online Car Clubs.. lol

 

As long as you aren't using the stock PCM to run the throttle you should be able to use it to run the dash and the MOP, etc. Even if it thinks it is in limp mode it won't matter...cause it uses the throttle to limit the engines output. AFAIK there aren't any other things limp mode will do

You likely need to adjust your AFR's around the 4K-6K range...when all 6 injectors come on where you have them staged you will get a **** ton of fuel

How do you have the injector staging set? Primary hold mode? Do some logs and see just how much fuel you are getting at the transition

 

Yup Primary hold just like the Manual says to set it to for an Rx8... Man so maybe leaving the stock ECU there to run the OMP might have to be done then..
I sent Eric Meyer another email, see what he thinks..

 

Don't eliminate lubrication from the squirters to their intended area. I have lots and lots of experience w this

 

Any other suggestions for this specific setup ? No stock ecu, using Haltech Sprint RE, how can that area get lubricated alternatively ?

 

Well depending on what the Cut Delay is set to on the Decel Cut, the injectors will continue spraying for a set amount of time after the throttle hits 0% so that will compensate and keep lubricating while shifting gears or any time the Pedal gets DePressed. Also there should be enough residue from a rich mix/map to remain in there in between shifts as well (that about the residue I'm just talking out of my *** but seems logical lol)
