Hi all

I am on of the only people in the NT that has a greddy emu. No one has experience with them here so does anyone have base Airflow maps for the Greddy pressure sensor, or do i need to collect the data on a dyno like this http://www.skylinesaustralia.com/forums/ma...p;hl=greddy+emu thread suggests.

I havent been able to drive my car for a while, so if anyone can help it would be great.

My car is:

1992 r32 GTS-t Auto - no mods

Thanks in Advance

Greg

(Also i am having issues with the car shifting from 850 - 1250 rpm when idling and the car running too rich, Do i just need a tune?)

If your maps are all at 0 adjustments then you shouldnt have a problem. download and run the file below, its got 0 adjustments and is set up for your rb20. as long as you've wired in the EMU right it should work 100%. I've also set up data logging so you can look at all of the right parameters when diagnosing problems.

Cheers, i was beginning to think no one used the emu

I'll see how it goes, i had trouble wiring it up initially and had to take it to one of the tuners here, apparently the injector connections were back to front someone had messed with the factory computer loom. He said that all of the setting were set to zero and hence i should be able to drive it around,

However....

Right now when you depress the accelerator there is a delay before the engine kicks in and at idle it pulses from 850 to 1250 rpm.

Furthermore once when i was driving it after it was installed, if i depressed the accelerator the car spluttered and sounded like it was going to stall, i then pulled over and restarted and it was fine?

Once again Thanks for your response, i appreciate it!

i used an emu for around a year, its a good piece of kit but it can definitely be a headache if not wired in properly. check if the map i put up fixes your problem, if not its possible its a wiring issue or even your jumper settings on the board of the EMU are wrong. also if it doesnt help i'd need a bit more info on whats happening to be able to help you out.

do you know how to read a data log properly to find faults?

Hi

I personally have not interfaced the the emu, i am a little worried about stuffing up my engine. So on Tuesday i am taking it to a tuner to have a look at it however since he has not had experience with the greddy emanage ultimate, i have to find all this stuff out myself.

So, so far i need to:

Open your file and update the emu,

Check the wiring and jumper settings,

Use the Data logger to find issues,

Most tuners in the territory are used to powerfc's, haltech's or Wolf3D's and since i dont know how to tune and have an automatic, i have to decypher the emu for the tuner i use.

Thanks,

Greg

yeah, all of my tuning was vs. psi.

plug in the sensor, set up the OPTION 1 or OPTION 2 (the 2 expansion ports on the front) to whichever the sensor is plugged into, plumb it into your plenum then off you go. its all in the manual.

i actually sold off all of my emanage stuff a few weeks ago including the pressure sensor and plug to input 5v from an A/F gauge.

you need to get yourself a laptop with the manage software and have a play with it yourself, especially when you're the one that is doing the research for your tuner. by the time i was getting someone to tune my car the first time i was explaining the features and helping with the tune. also helps if you have a minor problem and all it takes is a few clicks of the mouse to sort out.

Hi,

What unit do i need to use to utilise the pressure sensor?

Data Sampling Map

Do i use, Throttle Position, Airflow Hotwire, Greddy Pressure sensor, Relative Pressure or Charge efficiency.

Then i need to sample the data, Copy the data then paste that to airflow output map?

Is That correct?

Cheers

Greg

    • For these last 7 years of ownership, I've always had to use a small scissor jack under one of the front tow hooks to raise the front just enough so my low-profile jack fits under to reach my subframe jack point. I'm beginning to get annoyed of always having to do this. Are there any lower low-profile jacks that fit under the gtr lip on a dropped car?
    • Seat of the pants assessment of the new intake: The car is way less "doughy" when hitting the loud pedal, especially off idle when stopped or in traffic, I did use a cheapo lazer thermal thingo to measure the temp around where the pod filter got its air, it was between 55 - 60°C, in saying this the car was shut off and not moving, so the OEM intake pipe was not supplying any fresh air to where the pod was when the car was at least moving A weird bonus was induction noise on the throttle in the cabin increased a bit,  I was worried that I was actually going to lose some of that induction noise I love so much, outside though, when I got the daughter to do a WOT drive by pass for me, the induction noise has increased alot when on the throttle, not quite ITB doort, but well up there I'm extremely happy with the results and have been exploring the country roads in the region  As for house mods: 1.New front fence is up and is awesome, it really upgraded how the joint looks from the street, and the added security is nice 2. Electricians have replace some interior lights, and with more lighting in the garage, a few new motion detecting lights out the front above the garage, front room, and at the front door, which I have already found heaps helpful coming and going, also now has fancy pants CCTV all round the house The only hold point for power though is the solar and batteries due to supply issues, although this will happen over the next few weeks 3. I have done a heap of landscaping out the front and I'm almost ready to do a new small retaining wall with some nice blocks to replace the brick and cemented in rocks around the raised garden beds cemented in river stone "was the fashion at the time" the house was built. I currently have a pallet of retaining wall blocks and 2 bulka bags of 20mm blue metal to replace the wood chip that is in the raised garden beds around the house 4. I now have 3 big raised garden beds for out the back to grow some vegetables, about 70cm high, 200cm long and 100cm wide 5. My 2 compost bins are already pretty full with brown, green and kitchen waste from the landscaping I'vedone so far, but they will probably take a few months to break down, so anything else that gets chopped, trimmed, and kitchen waste will just start filling the base of the raised garden beds to about 30cm before I start throwing 40cm of good compost, and stuff, for the vegetables to grow in, I'll need a few ton of compost and soil, but the local supplier can sent me bulka bags of the stuff Basically the logs, wood chips and a few strategically placed rocks for drainage, will give the beds some good organic materials down low to break down over time, and they will hold moisture during the warmer months to save the water in my big arse water tank if we don't get alot of rain So, all in all, the car and house mods are going well, and I'm really enjoying being retired, I sleep in too 0700 and slowly plod around inside until I feel like actually doing anything, and only work in the yard for as long as want, which has actually been alot over the last few weeks,  although when you look at it, it seems that not a huge amount of work has been done,  until I look at the before I started the work pics Happy days and good times indeed 
    • hahaha yeah. Plan is to get side skirts and probably just rear pods. But going to do them one-by-one. I've got a set that I really like from RHDJapen, but that one isn't shipped to AU. So need to find someone who can get it for me
    • Here's an idea, answer the questions I asked you as they are trying to work out WHY the LSD will be binding up in a straight line.
