Calum / CalumRT Discussion

Post by **8-bit** » Tue Aug 07, 2007 5:06 pm

EDIT: (I hate to have to insert this, but FYI this thread was created when I was new and still learning. Much of that learning became better understood later in the thread. You may find a few ideas that are not clear or do not agree with discussion later in the thread. Go with the newer/fresher information that is discussed. I noticed an example of this in my discussion of setting the K and TTPmin in the first few pages where what I said was not really the best approach. Read and learn, and welcome to KA-T Tuning!) EDIT END.

I want to be the guy who starts this since I have a CALUM Realtime ECU. I bought it for around 375 because he provided the ECU.

So far I have made some really interesting progress in understanding the tuning, especially how certain variables and tables can be used to modify driveability, etc.

I will add to this thread a bit of what I have discovered, but first I would like to encourage any other Calum tuners to speak up and share any thoughts or tips that can be used to benefit the understanding of tuning the stock Nissan ECU.

Once I've got my binary a little more honed in to where it needs to be, i will post it. And if anyone else would like me to host their binary, i have a webserver that I use for all kinds of b.s. that I could host them on.

Rock on,
<3 me some Calum

The Calum ecu is kick ass. I've had it for a while now and it is a great product.

I've tuned a lot of stuff and have experimented with tons of different systems. Bikirom, calum, dual emu, single emu, etc. And so far the Calum has been the best.

But nothing can beat Nistune. Hands down #1 in my book.

I just looked up nistune.. looks cool. Pricing?

Just received my Calum and I will definitely be sharing anything I learn. I haven't installed it yet, but once I do, I'll be asking some questions and hopefully answering some too.

Around 400 AUD.

The first thing I discovered was that my car did not want to hold idle when putting in the clucth from 2500+ RPMS or free revving the motor out of gear. It would just drop down and die. Fortunately I have a PLX wideband so I was able to see it flash RICH right at the point it would die.

The TTP min settings in the lower RPMS are , what i found to be, values that are not affected by setting the K value (injector scaling). Thus, when my car was dropping RPMS it would put in 'X' amount of fuel based off the TTP min thinking I still have 270cc injectors, but it would be using my 670cc's! And thus it would get piggy rich and just choke out.

I also remember having to open up my IACV idler screw as much as possible. It was only like 2 turns out, but after opening it substantially it made her catch the idle drop much easier.

I ended up taking all the TTP min values below 2400 rpm and halving them. That seemed to do the trick. I might actually go back and lessen the values some more. Since I have done this my car has not stalled or died once. I have my idle set at 925 (because with these hard motor mounts the vibrations at 750 sucks) and it will dip down to 500-600, then pop up to 925 right away.

BTW: I have a fidanza 11lb flywheel.

Other than email, does anyone know how to get in touch with this guy? Also, what was the turnaround time between when you sent in your ECU and when you got it back. Also, what software do you use to tune? Is it something custom that he made or what? Just looking for a few details before I decide to buy a bikirom.

I'll PM you his cell number after this message. I think he has a traveling job, but i know he could probably get it done and back to you within 2 weeks of receiving your ECU. Probably sooner... (i'm no spokesperson for calum though, so dont' quote me).

The software you use is TunerproRT, which is a somewhat freeware tuning program. You can pay 30 bux or something, or you can just wait the 10 seconds delay for not paying. You have full software usability even without paying.

Calum also sets you up with a consult-over-USB port that streams your nissan consult data. You can use some of the various freeware nissan consult software, or you can get what most of us truly enjoy, Nissan Datascan, by blazt. It costs like 30-35 dollars. It taps right into your USB port, you get full on consult use, and Calum can provide you the appropriate numbers to input so you can have REAL FULL TIME MAPTRACING on fuel and timing maps!

Did i sell you one yet? Hah.. they rock.
Also, if you really are DJ Hype, that is awesome. I've been a jungle/dnb head for 12 years now.

im going to be investing in some sort of tuning soon, and with so many options out there.. I don't know what to go with. From what I've read about Calum, it seems everyone loves what he's done. But before I make that investment, I'd like to see some numbers that people are running with Calum ECU's. I'm looking to be able to run a solid 350whp and there is a possibility that I will want to eventually break the 400 mark. I'm thinking about bumping turbos from a t3/t04e .50trim to a .57trim to allow for this hp gap. Will the Calum ECU be able to help net those kind of numbers? And if so what kind of stuff is involved? And also, are you able to remove the speed limiter?

sil8ty · Post by **sil8ty** » Wed Aug 08, 2007 11:12 pm

You can remove the speed limiter, reset the rev limiter, and do full tuning of fuel and ignition maps.

I run an sr20det w/gt2871r @ 1.4bar no problem at all. It can go more but I like what little response I have.

put it this way... a Calum ECU is like a romtune that you can do in real time... So if you have seen a JWT or Enthalpy tune do well, you will see the exact same out of a calum tune. While JWT and Enthalpy tune safe, and many people use SAFC2 to get it into the prime, your realtime Calum ECU will be able to tune all to your hearts content in regards to nissan ecu tuning.

IMHO, the only thing better than a Calum is a full standalone like Microtec, Autronic, or AEM EMS. I haven't tried anything else except a failed attempt at making a bikirom work... But I will tell ya this, the streaming consult is pimp **** and the tuning is spectacular.

rockon.

Not yet... I think he's working on it.

hey would it be possible for the 95 od1 ecu to work with the calum ecu

Yes.

Here is a link with a description of the ECU:

I had a Calum Realtime ecu in my Ka-t, I totally loved it. It is easy to use and tune with once you get a feel for what you are actually doing. I really think it is the best ecu for a lot of people out there, and it is hard to beat the price.

MyRedS14 · Post by **MyRedS14** » Sun Aug 12, 2007 5:04 pm

What did you switch to?

Do you have any Calum tunes sitting around?

el tigre · Post by **el tigre** » Mon Aug 13, 2007 1:19 pm

I have a few tunes, it has been a while since I have messed with this stuff, though. I sold my 240 in the spring and am looking at buying it back this week, I hope so anyway, lol.

What tune do you need?

MyRedS14 · Post by **MyRedS14** » Mon Aug 13, 2007 1:43 pm

Just something to compare it with the base tune that I have. I'm gonna get it tuned, but I want a reference to what I already have.

Set-up is in my sig...

el tigre · Post by **el tigre** » Mon Aug 13, 2007 2:21 pm

You could have had Calum put the Enthalpy tune on there for you, then you would know what you have at least. What MAF are you running?

MyRedS14 · Post by **MyRedS14** » Mon Aug 13, 2007 3:40 pm

I would have had to send my Enthalpy ECU to him, and I didn't want to pay for shipping. I have someone local that can take the bin from the Enthalpy; it's just a matter of making the time to drive to him...

I have the N62 MAF.

Post by **8-bit** » Mon Aug 13, 2007 4:17 pm

I'd like to see the tunes posted in here! If you need someone to host them, e-mail them to gd_el@yahoo.com with a description of the setup it is for and I will host them and post them!

When mine is more 'spot on' i will post mine.

MyRedS14 · Post by **MyRedS14** » Mon Aug 13, 2007 6:28 pm

I'm definitely up for the whole tune sharing thing. It'll be a little while before I can get it tuned and then on a dyno, but as soon as that happens I'll post up, or PM whoever is interested. I'll mostly have tunes for 91 octane (no good gas in Cali), maybe 100 octane and most likely E-85.

As long as everyone agrees that it's use at your own risk...

el tigre · Post by **el tigre** » Mon Aug 13, 2007 6:48 pm

I have a 15 psi tune, or less, tune for N62 550cc's, blah blah blah. It is NateDoggs tune. I will get it to you soon as long as I remember, lol.

Post by **8-bit** » Mon Aug 13, 2007 8:57 pm

post or e-mail me all your goodies and I will consolidate to one large post with descriptions and hosted binaries.

el tigre · Post by **el tigre** » Tue Aug 14, 2007 4:19 pm

That sounds like a plan, I don't really have that many, just a few various setups and alterations. I will try to work on organizing them soon, when I get some time
