hey ive tuned your car!!.. Twice! Stop your whinging!

& No can do Titan.. you got stock turbo.. i am guessing it would break on your first anti lag.

ignore that bit i want the wanky idle :) the antilag would have an arming threshold of 8000rpm and 100% throttle. but you have to have it on for the ilde so running 0 degrees ignition retard with an arming rpm that i wont reach will mean it never triggers and my exhaust wheel remains out of my cat.

I know you have, and it's still alive! :banana:

It would be in skyline heaven if I tuned it :)

Guilt-toy is a gun tuner...im going to get him to look at my 13th century medieval harp as well.

im going to be installing my vipec tonight so i can get it in before my engine is started. ive got a few questions.

i want to hook up my wideband to it, where do i get the expansion loom from? how much are they?

i read in the vipec manual that you had to use a 1mm restrictor for the map sensor, has anyone done this? i was doing this with my greddy 3bar map sensor to keep the boost readings steady and it worked really well (except i had to use a 0.3mm restrictor).

which wires does the IAT sensor connect to?

IAT has to be wired in yourself to any of the AN Temp inputs (mine is on temp3 (expansion connector)), you can wire your wideband up through the NB oxy wires (AN Volt 6).

My map line doesn't have any restrictors in it.

The Vipec dealer can supply the expansion loom. Alternatively you can solder direct to the board (I did for my boost switch)

i wouldnt solder onto the board, re-sale of it would be less if it was tampered with i think. is there a PC part out there that will work for now?

I don't plan on selling it, so resale is not a problem...and it can be removed in no time at all :happy:

I looked for a suitable connector at Jaycar, but couldn't find one. The pin spacing is very small.

Sounds great. I have an overboost problem at present and wouldnt mind checking out whether its teh boost controller thats causing the problems without buying an expensive new one. Solinoids are 100NZD (not sure about AUD) if you want a new one also.

Look forward to hearing how it goes mate.

Got the stock r33 RB25DET boost solinoid working with the Vi-Pec on the weekend. It works very good. Honestly if you spent a little extra time with the boost controller settings you could get it to have a very very flat boost curve. Mine spikes a little but i was happy with the way it spiked.

You need to program the duty cycle per load point. So if it spikes you add duty number, if boost is too low you you remove the number. Took me AGES to work it out. but once i got it worked out I got decent boost pressure AND....

I did get 511rwhp with e85 but it was running very very lean up top because i was out of injectors. So yeah very happy with my flat power curve from 135 to 180 all the way it has 2hp more or less then 500 :thumbsup: ! Just how i like it. Useable power revs.

Changed back to pump

The more I use my Vi-Pec the better i am getting with it, Twoogle was a breeze to tune as well.

So yeah another win for this great ecu. Cost me 0$ for electronic boost controll and its only a 2 port solinoid!!

GT, after all ur playing around.. how long do u think it will take a tunner to go from standard ecu to a full tune that includes all the cool stuff the vipec has to offer, such as setting up anti lag launch control flat shift cycle idle. and getting the boost control fiarly dialled in??

there is alot of setup there mate, like

- Install ECU and run map sensor

- Install air temp sensor in pipe and run wires

- install digital input to clutch switch and run wires

- Set timing on engine

- Map ecu for cruise and boost...

Thats a big mission.. I would think it could take 4 hours totally completed by a Vi-Pec experienced tuner. He would have to be good at what he does and know how to do it and has done it with this ecu a few times.

I did notice with pauls car that when i was setting up and getting ready to tune I was flying through the setup and getting all configured and working ready to tune in no time at all.

So yeah 4 to 5 hours if nothing else goes wrong - Drive in - Drive out deal.

I would love to see someone setup a Power FC and tune it in that time, setup a aftermarket boost controller and setup a aftermarket launch interface and then your still missing anti lag and PROPER flat shift with time delay and timing retard.

So yeah this ecu is friggin awesome now, once its actually fully finished and developed properly (Ray hall is continually working on improving it and adding features) it will be a pretty damn good first choice ecu for all applications.

    • Yeah, that's fine**. But the numbers you came up with are just wrong. Try it for yourself. Put in any voltage from the possible range and see what result you get. You get nonsense. ** When I say "fine", I mean, it's still shit. The very simple linear formula (slope & intercept) is shit for a sensor with a non-linear response. This is the curve, from your data above. Look at the CURVE! It's only really linear between about 30 and 90 °C. And if you used only that range to define a curve, it would be great. But you would go more and more wrong as you went to higher temps. And that is why the slope & intercept found when you use 50 and 150 as the end points is so bad halfway between those points. The real curve is a long way below the linear curve which just zips straight between the end points, like this one. You could probably use the same slope and a lower intercept, to move that straight line down, and spread the error out. But you would 5-10°C off in a lot of places. You'd need to say what temperature range you really wanted to be most right - say, 100 to 130, and plop the line closest to teh real curve in that region, which would make it quite wrong down at the lower temperatures. Let me just say that HPTuners are not being realistic in only allowing for a simple linear curve. 
    • I feel I should re-iterate. The above picture is the only option available in the software and the blurb from HP Tuners I quoted earlier is the only way to add data to it and that's the description they offer as to how to figure it out. The only fields available is the blank box after (Input/ ) and the box right before = Output. Those are the only numbers that can be entered.
    • No, your formula is arse backwards. Mine is totally different to yours, and is the one I said was bang on at 50 and 150. I'll put your data into Excel (actually it already is, chart it and fit a linear fit to it, aiming to make it evenly wrong across the whole span. But not now. Other things to do first.
    • God damnit. The only option I actually have in the software is the one that is screenshotted. I am glad that I at least got it right... for those two points. Would it actually change anything if I chose/used 80C and 120C as the two points instead? My brain wants to imagine the formula put into HPtuners would be the same equation, otherwise none of this makes sense to me, unless: 1) The formula you put into VCM Scanner/HPTuners is always linear 2) The two points/input pairs are only arbitrary to choose (as the documentation implies) IF the actual scaling of the sensor is linear. then 3) If the scaling is not linear, the two points you choose matter a great deal, because the formula will draw a line between those two points only.
    • Nah, that is hella wrong. If I do a simple linear between 150°C (0.407v) and 50°C (2.98v) I get the formula Temperature = -38.8651*voltage + 165.8181 It is perfectly correct at 50 and 150, but it is as much as 20° out in the region of 110°C, because the actual data is significantly non-linear there. It is no more than 4° out down at the lowest temperatures, but is is seriously shit almost everywhere. I cannot believe that the instruction is to do a 2 point linear fit. I would say the method I used previously would have to be better.
