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!

    • Pressure when IDLING, is meant to be 51PSi... So that amperage value needs to go up a fair chunk... I'd personally be factoring for more like 12amp at least on those runs, and at that point you need to hope the already there wiring doesn't drop you a volt or two, as that's a lot of fuel pressure flow drop off from 13.5 to 12V! Taking idle pressure of 51psi, means the pump will be drawing a MINIMUM of 9amps all the time based on your reading of the graph (3bar base, then allowing an extra 0.5bar for boost = roughly 51psi)
    • Hi all,  I am in the market for an R200 longnose diff out of a Z31 300ZX, or S12 RSX, DR30 skyline, or similar, in a 3.9 ratio.  Preferably a late model one with the M12 crownwheel bolts.  The only easy to find advert for one of these was my ad back in 2007 when I sold it on this forum.  I sold the diff as I had sold the car it goes to, but as it turns out, after 18 years I got the car back late last year, so now I'm looking for the diff !  If anyone knows where to find a longnose R200 LSD with the M12 crownwheel bolts, drop me a line at [email protected] - Bonus paid if soomeone comes up with the original diff (stranger things have happened !).  Cheers   Ben D    
    • Hi everyone, I used to post here a bit from 2004-2013, when I owned various Nissans, in particular my S12 RSX gazelle, which was sold in 2007.  As luck would have it, after an 18 year hiatus, the car found its way back to me last year, and over the past 11 months I have had the pleasure of restoring it with my kids.  One thing that I am after in particular is a 3.9 ratio R200 LSD for it.  I actually sold the one out of the car here back in 2007 , and it would be incredible if I could track down who I sold it to, so I can see how they have progressed over the years (and to be honest, to see whether I can get the diff back !).  Anyways, hi all and let me know "where are the R200 Longnose diffs all at these days ?  Cheers Ben D  
    • Arms will be the same as the G35 or 350Z, but as above, there was a change in the lower control arm where it connects to the ball joint.  That said, you can remove the ball joint cone from your old ball joints and fit them to the new ball joints.  To be honest, I didn't think the ball joints themselves were different. The main ball joint is a bit awkward to replace, you really need to remove the steering knuckle to press out the old one.  Some people have used tools to remove it in place, but it just seemed too hard to get to. If you are going to press out/in that ball joint, then you may as well just replace the bushings in the LCA and the compression rod.  You can buy the compression rod bushing from Nissan, but the LCA bushes, you will need to go aftermarket. Much cheaper than buying the whole arm.
    • Ha, well, it's been.... a bit of a journey. Things have taken much longer than I'd hoped. I'll probably put up a thread at some stage. Hopefully soon. The car's not done any kms since my update in June though, put it that way.
