just picked up my vi-pec plug in board and a boost controller solenoid.

if you go with the vi-pec solenoids you'll need to get some 1/8th BSP hose end fittings from somewhere like autobarn or auto-pro etc.

what i noticed was the solenoids looked very similiar to my profec b spec 2 solenoids, i asked scott from insight motorsports about this and he said that you could use a profec solenoid as it is pretty much the same thing, you just need to cut the loom off and wire it in.

Id be interested to see whether anyone has bothered to run the boost controller that comes with these computers. The guy whos retuning my car was part of the development team of these new ecu's and said they are incredibly good.

Wouldnt mind hearing some other opinions as naturally he is a tad bias!

Cheers

i am running the boost controller built into the board through the stock GTR solenoid and it works perfectly

well at least it was til i blew big end bearing and pulled car off road to rebuild

Ray seems to think its possible so I'm going with the stock GTR solenoid.

Taken from the help file with the vipec software.

The number and spacing of the cells in the Table is completely user adjustable. Rows/columns may be inserted or removed where desired by right clicking in the desired place on the labels of the RPM Axis or Load Axis (ie right click on the RPM values to insert a new RPM column). This flexibility allows fine spacing in areas where high resolution/accuracy is required and coarse spacing in less critical areas. The maximum number of RPM columns is 22, while the maximum number of Load rows is 20. When adding a new row or column, the new row/columns cell values will be interpolated between the values in the rows/columns which it was inserted between.

440 maximum load points in each map

And Autronic has 18load, 32rpm. Does that sound correct?

So 576 to 440 points

Yep, but you must have a LOT of time on your hands if you intend to try and tune all of those cells...

The interpolation works very well on both ECU's so you dont need anywhere near that amount of cells in reality if you're only using a revlimit around the 8000rpm region.

I own both an Autronic SM4 and a Vipec V88 and I'm not using the full resolution on either ECU.

Roger that, I agree. I guess for an engine running to 15,000 rpm the extra points may be more useful.

The reason I ask is I was very close to purchasing an SM4 @ $2100(trade price) but really like the idea of a plugin ecu, especially in the std casing. As far a I can tell, all I need is a knock amp to gain all the features I could possiblely need for my motor.

Is there any other functions apart from increased resolution that the autronic has over the Vi-Pec? or visa versa?

Is the cost of the RB26 plugin $1650? or more expensive since it has a built-in MAP sensor?

I am the same, i have a autronic in another car and its awesome, i want to try the vipec but i HATE being burnt by new products, seem to stick with the known good now.

but it seems good and im getting OVER pfc missfire.

Just went up...they are now $1760 inc gst.

yeah but its nice to condense the resolution near peak boost torque areas or where fast increase in boost and rpm occur to get a nice fuel and ign curve etc. Nothing worse than having big steps and relying on interpolation on big hp cars.

Had a tubbed pro street car making 700rwhp in last week with a "?????" ecu and the resolution was a real issue.... lazy high nine 1/4's on street rubber but i know it could make more power, run quicker, be more driveable (as its a pro street car) and use far less fuel with a different ecu.

Just got a quote yesturday for $1663 inc +$20 to upgrade to a 5bars MAP and $280 for a knock amp

must be old stock as all new stock ordered after the 1/2/09 is under the new pricing.

grab it while its cheap!

    • Hi. Sry iam not a mechanic and iam not at the car atm so i dont know 100% but they told they measure those and even try to change those. AFM they have two. Coils are new a they have my old one too. Plugs too. ECU...we have 25 NEO stock and Nistune 25 NEO.   But i dont know if any one those could be the problem and why/if/what can cause this, Only thing they did not check is fuel...but that walbro 255 is new(like 1,5 years)... That fuel pressure gauge idk...but i let them know Any suggestions?   EDIT: how can they know if it is like you say he ECU pull power when it reaches a specific boost level that is too high? Tha car has boost controler
    • Can you clarify what you mean by boost cut, do you mean it misfires both when under load (driving) and when stationary and out of gear? Or does the ECU pull power when it reaches a specific boost level that is too high (boost control issue)? Does it occur at idle with no throttle? When you say "the ECU is OK", what ECU is it and why do you think it is OK? Have you used the NEO ECU, and if so do you have a MAP sensor attached? Same for the AFM, why do you think it is OK? Do you have any way to put a fuel pressure gauge on it (even just a mechanical one between the fuel filter and fuel rail)?
    • Hi.. Just another problem. So maybe you can help. I(my mechanic) done swap from my RB20DE NEO to RB25DET NEO. Everything is OK but we have a boost cut. Coils/Plugs are ok...AFM is ok. ECU is ok. I have Walbro 255 but it "changed" sound few months ago(you can hear it ouside) you did not hear that when it was new(maybe faulty?) Sooo...what now? What can cause this boost cut? It is even when you standing still...
