Oil Metering Pump Tuning with Interceptor-X/Microtech
 

I'm taking under the assumption that the oil metering pump is still controlled by the stock computer with the Interceptor-X/Microtech. If so is there anyway to increase the oil metering pump voltage then?

I'm wondering because I would think a little more oil would be required with a turbo engine then the stock N/A. Anyone have any ideas?

Premix...it works better and is more consistent....

Well premixing is fine for someone that treats their car as a summer/weekend warrior but for someone that wants their car to run like a normal car all season without carrying cases of premix around that really isn't an option. Especially for the rx8 which requires more frequent fillups. Or at least its annoying as hell for someone who doesn't treat their car as something more then a car.

A little info, this is not my car and is a customers car I am tuning. I do own an RX-7 and the PowerFC ECU has a function to bump up the OEM oil metering pump voltage by temperature. I only dab a bit of premix when I go to the track but otherwise its stock oil metering. This works well as the housings dont show any sign of excessive where when I open the engine up. I drive the car often and take it to the track often as well (26,000 km so far this year with over 10 track days).

I would just rather not tell the customer, "you installed a turbo so now you have to start premixing because we're unsure if your engine will wear quicker then normal".

Get rid of the IntX and flash tune or premix . Those are your only options .
Anyone who has a turbo fitted should understand that additional maintenance is a good idea . Can't see why you can't just tell him that .

premix is a must for an NA Renesis even; it's a design flaw
it would be beneficial to tell your customer to premix IMO

If you carry 1 quart around you have lots for quite a few tanks....and for the peace of mind he would be foolish not too.....You can flash tune it to up the OMP flow...but it isn't a voltage thing to get more flow.......

Use both the AP to bump the oil metering and the INTX to maintain the other variables, currently I don't premix and have a larger turbo and have yet to see a need for premix.

The engine has 10k miles on it with the turbo kit but those miles were heavy spirited driving, autocrossing, and just flat out having fun with it.





This kit has been on my car for over 2 years now without major issue.

Thats actually a very good idea. The customer does have an accessport so I could ask him for it. I just didn't know what you could change with the accessport as I have never played with it.

I assumed the RX-8 oil metering pump worked the same as on the RX-7. Basically it is mechanically controlled by RPM and the computer controls the voltage to the oil pump. As water temperature goes up, the voltage is increased to add more oil.

The only reason I even add premix at the track is because the 3mm ceramic apex seals should be more agressive on the housings as they don't wear. So I add a little extra oil for extra insurance when I'm beating the car hard at the track. If I was using stock type seals I wouldn't even bother.

If he has an AP he does not need the InterX. Waste of money. The AP will do everything needed related to tuning and engine management. Including the OMP output. One package and simple.

That is not what the seller of the of the turbo kit (Esmeril Racing) thinks. He says the accessport is junk for a high boost RX-8 and would likely lead to motor blowing.

Also, using a MAP over a MAF is preferred in a turbo car for accurate tuning. So I sort of understand where he is coming from.

thewird

How much boost are you going to run? If you don't mind me asking?

I'm aiming for 12 as I honestly don't trust the RX-8 seals with high compression rotors to take the abuse of what I normally tune say an FD to which is 16-17 PSi. I understand it needs less timing and a touch more fuel and will be testing timing on the dyno once I get the car running mint tuned on the street.

My starting timing map is pretty conservative to begin with, as I basically took the timing I run at 15-16 PSi (on a streetported FD motor) and put it at 10 PSi and filled the timing around that. More or less anyway.

If the owner later comes to me asking for more after a month or so of driving, I will tune it to 15-16 but he has to understand how on the edge it is for his stock motor. We do have Sunoco 94 octane available locally everywhere so thats kindof a plus though. If he gets some sort of injection, I would feel a lot more comfortable though.

thewird

He is correct, and I would agree with you as well.

I have run 14 psi and up but like you said it really puts the car's motor on its edge. I run 8 daily and 14 psi for fun. My flow would be slightly less then the esmeril kit if I am not mistaken so 12 would be best actually, running the higher octane he should be able to go even further.

Selfless plug for MM...lol

Why are you in this conversation you don't have a boosted RX-8, there is a difference in principles and applied knowledge versus real world experiences and results. Not to mention your recommendations is actually in rather poor judgment without supporting claim.

I think thewird is trying to get safe, reliable tune with a good EMS, the AP just can't do it with the setup such as the esmeril kit.

I don't completely agree. The MAF tuning vs MAP tuning is undebatable (sp?). Both systems have got their pros and cons like everything in life, our MAF has got some scaling limits though but i don't think that those will be reached with the airflow you're going to see.
The real junk piece should be the microtech computer inside the interceptor-x in case, i'd rather rely on a motec or a haltec for that same purpose. 2 different worlds imho.
The problem is that MAF tuning requires an accurate sensor position, be it blow or draw through you need a straight tube of the correct lenght\angle capable to feed the MAF with straight airflow. Something the esmeril kit isn't famous for and the reason why (i think ) it adopted the int-x (the only cheap alternative to serious stand-alones).

lol


:rofl:

:yelrotflm:rofl::lol::lol::knob:

Believe it or not I am actually using both right now the AP and INT-X with some good results.

I am quite certain that if Chris really WANTED the Esmeril kit to work with the Cobb AP that Jeff could help him be successful with it. All this bullshit is never a matter of objective logic, anyway. It is largely one of a given tuner's preference.

Selfless plug for MM,, Not at all. He pay's me rather well.

What's the matter Brice? Having a bad day?
And why are you in this conversation? You know nothing about tuning.
Which is evident by the last Turbo Fluid installed on one of your customers cars?

Oh look your selling the Turbo parts for the customer.

Oh look supporting claim.

Here is an Accessport customer with the MM Turbo Upgrade and pushing lot's of reliable power and torque. selfless plug for Chickenwafer.
330rwhp and 326ft-lbs of torque @ 13.5psi!!
Tuned with an AccessPort.

Now go butter someones buns Brice and sell another turbo kit. You pusillanimous twit.

lol
I luvz me sum $5 words!

Easy not all of his turbos have blown.
You forgot 05rex8 who has Fluids Greddy Turbo Upgrade...
then again, he didn't even make 300HP with it, not even close.
Heck, in this thread he states he's already thinking about changing it and going with a different (better) upgraded turbo.
Guess Brice knows nothing about turbo's either

You really are a dumb shit. We never even got a chance to tune the car. Once we got it in the car in our hands and after the installation had been completed a compression test was completed by us and the customers car was on the verge of going out so the customer made the decision to part out and get rid of the RX-8.

The sad thing is a week before he had the installation completed the car was at Mazda for engine diagnosis....

But you already know the whole back story you schmuck.

Not to engage into further debate but we werent even there for tuning...the tune if I am not mistaken had been completed by MM with his E-Tune services.

And by the way none of our turbos have blown.

Despite all the nonsense and drama, if you would like any help or advice on this feel free to PM myself, Easy_E1, MazdaManiac, or Flashwing and we would be more than happy to share our opinons with you. BHR has a long history of helping out other professionals to have the best outcomes possible with their installation and/or tuning jobs as well as a long roster of references. We have our opinions, others have theirs, and you can decide for yourself which is the more comfortable route for you.

Ok I need to clear some things up here.

First of all, 284rwhp is not that far from 300rwhp.

Also, if you keep reading that thread you linked, Brettus gave me a suggestion in order to work the kinks out of my current setup. This was something I over looked and is not Brice's fault. So I apologize if it looked like I felt I got ripped off. I probably should not have worded things that way to begin with, just some frustration coming thru in my post. I've had so many headaches with this car in the past year because of FI. In fact I have edited that post, as it was not accurate.

The greddy actuator is garbage for an upgraded turbo. Plain and simple. The upgraded turbo Brice offers is a decent alternative over the stock unit. According to Bryan at BNR it is a great compressor wheel. However the wg actuator needs work, which again I overlooked and was not his fault.

Brice, again, I apologize for that post. It was my bad since I didn't research fully.

sorry for the threadjack
