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.

      Depends how low and tyre size. Should fit with natural camber, skinny tyres and rolled guards.

      Was planning on getting an R35 MAF and the adapter, should this be okay? Also any idea where I could get my hands on an intake pipe?

      I mean yes, if you're starting from scratch on an unknown engine yes you don't need to be doing all kinds of math in the background but if you're doing relatively minor changes like AFM + injectors + boost up with some aftermarket turbos it takes quite a bit of math if you want to do something like maintain OEM fuel + timing tables but compressed and then a bit more load scale up top. I think I've spent too much time working on big engineering nightmares though so I'm a big fan of trying to constrain the scope of whatever work I'm doing as much as possible and trying to get it right before moving on. For example, a local owner just did the usual E85 + single turbo conversion to his R32 GTR and nearly burned his car to the ground doing some spirited driving up the local mountains. Turbine is unshielded and too close to the hood insulation. It's tough to balance "just get the project done" and "seemingly small details can cause massive setbacks I'm not willing to deal with".
