I still have my Calum box. I've grown up to standalone on all of my builds now. Haltech are the bees knees. So is volumetric efficiency tuning. I'll never forget my roots of where I started though, with all of you guys. ^_^

My original Calum crapped out on me a few months ago, so I went on to nismotronic. We got a calum unit for my dad's car but to keep it simple we're going to sell that unit and both run nismotronics. Like you guys I remember figuring all of this stuff out 4+ years ago. Thanks for the info.

It is very important to temporary disable all the ECU self correction before tuning the K Constant and the injector latency.
use this formula to find a base k value: stock K-value (old inj./new inj.) x (new maf/old maf) = new K-value EXample 39720 (275/550) X (500/290)= 34,241

So start with 34,241 and 720 latency.

1. Unplug the stock O2 sensor, the O2 sensor signal will default at around 0.33 volt, (even though 0.33 volt is a lean signal to the ECU, the ECU won't use it as a reference if you have complete the next step).
2. In the main fuel map, view the map value in "Raw Value". Only in "Raw Value" can see which part of the fuel map using O2 feedback correction.
value 0 = target A/F ratio at 14.7 WITHOUT O2 feedback correction
value 192 = target A/F ratio at 14.7 WITH O2 feedback correction
Change all main fuel map low load area value to "0"
3. The injector latency affect the short injection pluse width more (ie : low load and off throttle) and the K Value affect the long injection pluse width more (high load, hi rev and on boost).
Start tuning K Constant and the injector latency by holding the engine at 3,000 rpm without loading at neutral, adjust the K Constant and the injector latency balance to achive or close to 14.7 actual A/F readings, check the idle mixture, try to keep the actual A/F reading between 14-16 across 800 to 3,000 rpm with slow throttle movement.
4. Change the main fuel map high load area to value 43
value 43 = target A/F ratio 11.0
Adjust the K Constant and the injector latency balance to achive or close to A/F 11.0 at full throttle 0.8 bar of boost, start increasing the rev range if the A/F readings is correct, check the idle mixture again, try to keep the actual A/F reading same as the map value.
With a correct K Constant and injector latency, the actual A/F reading will be very close to the fuel map target A/F ratio.
Only tune K Constant and the injector latency when engine is fully warm up.
Only a clean AFM will give out correct air flow readings.
Only flow balanced injectors give out true A/F readings.
Only start the tuning when all sensor signal is correct, such as throttle posistion sensor at 0.45V - 0.50V on idle ,idle switch and netural switch signal is on (when idle and neutral, both switch signal will showing in red color).

In the final stages of tuning you need to make changes to reflect 11.5 to 11.8 afr's at full boost. :lol:
great post and interesting way to tune K and lat.

hello i have had this ecu for years but wasnt able to use it nor find someone to tune it anywhere. i sadly and honestly dont understand it and i have read it over and over again. what other route would be easier and not expensive like aem but that ppl can work with?

more of a suggestion than a statement, sorry. they 100% have the knowledge to tune it, wether they actually will is a different story. if you have tunerpro and calumsult on your comp i would tell them you have a ll the software etc and just need someone to dyno tune it. they may not be familiar with the specific ecu but tuning maps is tuning maps...

BOOOOOOO!!!!!!!!!!!!!!! dude you sound smarter than your giving yourself credit for...... this **** is not THAT hard. that plan is admission of complete failure. now your gonna go drop like 5-700 on another setup!?!?! if thats the case sell urs for 400, and take the 5-7 u were gonna spend, go buy and AEM or haltech and take it to RACELAB.

do u have s14? a guy on our local forum is selling JWT ECU injectors (96lb top feed) and lightning MAF for 300$ but its going to piss me off to share that link with you. your totally capable of tuning your car. plus it seems to me FL is a HOT spot for activity, SOMEONE down there can tune it.

Yes Enthalpy ( Martin) is here in Tampa. Works out of a shop called Z fever. Has been making serious machines for a long time. Cool dude give him a call if you go that route. He can even dyno tune your car for you.....if you pay obviously.

So...I'm pretty interested in this Calum ecu. I'm running an Enthalpy tune at the moment that is a 93 octane/e85 tune for 740cc nismo injectors, n62 maf, and stock block/cams. I haven't read all 43 pages but Is there a way to copy the enthalpy tune onto the calum ecu for a base to tune from?

I have one ecu with the enthalpy chip and have a spare one I could have the calum board installed on. If not I could always try selling the enthalpy tune (works great) and buying calum. My only problem with the enthalpy is that I run pretty rich, which could be because I'm on the stock FPR with a walbro 255 or possibly my tiny boost leak)... but I would like to be able to customize my setup without sending it in for a retune any time I change injectors or something.

Calum has stopped doing this a long time ago, probably 4 years. I have an extra Calum RT ecu that I am willing to sell. I would hope you could ask Enthalpy for the tune file so you could put it on this board but that will be up to you. The stock fuel pressure regulator works fine with a walbro 255lph, but you should really fix the boost leak.

Let me know if you would like to purchase my ecu. It will be plug and play with any KA24DE S13, for S14 you will need a jumper harness.

Whats up guys, I need a bit of help with datalogging with a CalumRT ecu. I understand this is ancient hardware, but hopefully someone can help me out.

I have installed all of the software including Calumsult, Calumsult-LW2 Beta, and Calumsult-TP Beta. All of the programs are working properly, including the tp portion of the TP Beta. The issue I am having is that i cannot seem to stream any of the calum data into Logworks. From all of the posts i have seen, its seems it is as simple as running the calumsult program and then opening logworks. This is not working for me. I think i know what my issue is, but would like some confirmation.

Do i need to have an innovate wideband streaming into logworks for the rest of the data to be pulled from the Calum ecu? Im currently running a plx wideband.

Thanx

does anyone still run calum? if so, have you all had any issues getting it to work on newer computers? i can get calumsult to hook up so i cant do anything

make sure your FTDI drivers installed correctly. your problem is not well described so you may not find help until you go into specific details that people can consider... operating system, what software you're using, what has or has not worked, what signs from the ECU you have seen, etc etc etc...

Try what 8-bit said. Update your FTDI drivers. Go to http://www.ftdichip.com/Drivers/VCP.htm and download the "setup executable" file in the windows row under comments. Also, the calum ecus have a battery to allow you to modify tunes without being connected to the harness. Make sure your battery is not dead.

After that, install TunerproRT and see if the program recognizes the ecu.

There is actually a Calum Quick Start guide that took me forever to find because most of the old calum links are broken.

emo_tactical9 to the rescue LOL. Check out the link below for the document.

i understand that was kinda vague... but 8-bit you know ive been around calum for quite awhile.. i got tunes and stuff in the hosted and posted... i used to have a dell xps that was a very early vista computer and all i have to do was run as administrator on sp2 and it would all link and work fine... but it crashed while my car was wrecked,, and ive since fixed my car and ive tried a couple different of my friends laptops with no success... it took awhile to actually find a working download for calumsult, but basically i was trying to get the xdf and bin on there that allows for s14 launch control and i never could get it sync'd up to load up the new launch control bin... the computers i tried were newer versions of vista and windows 7 laptops, i dont know that ive ever tried those drivers though. i didnt know anything about them

and every time i haved tried to sync its been plugged into the harness in my car with the key on

Jwrose. Prove it works on an old windows machine, then try compatibility modes in windows 7. Talk to a friend with lots of IT skills and see if they can get it to emulate windows xp for the drivers and the software. It may just be broken....

I will see if I remember to add that stuff this week. If I don't add it, pm me. I'm a busy guy and I have limited time. Right now, via smartphone.
