Hi Grizzly,

The ultimate on ebay at the moment is £379 + £10 postage so it is about the same.

Hi Prof,

Shame about the ultimate not being compatable with the profec E01, Besides that you think this will be a good alternative to the PFC?

Cheers To all Garith.

Do you need to fit a Loom to use it?

[GaseJo]

It comes with harness and software for setting up for that price

[Grizzly]

Ok, So its abit like the Microtech Package, Who in the UK sets them up? or are you planning to do it yourself?

[GaseJo]

I dont know who will set it up definatly not me, the bloke who i got to fit the profec e01 and e-manage to my skyline probably. I will have to see but at the moment i have not made my mind up on what route to take just getting some insight into it all.

Cheers Garith.

I got my Ultimate and full harness for around £370 including import and what have you from the US.  It even came with US English manuals as well as the Jap ones !

Seems easy enough to wire in, but you can also get a \'boomslang\' harness adapter that fits between your existing loom and ECU so you don\'t have to cut any wires - these are about £100 by the time you\'ve imported.

You also need to source a wideband O2 sensor and controller - the Innovate LC1 is a good match, and if your running higher boost levels, either the Greddy or GM 3 Bar MAP sensor - I got the GM one off ebay for about £40 including post.

You can run it as a datalogger only to get you started, and then as confidence levels rise, you can start tweeking the various maps.  Since it\'s a \'pass thru\' device, the stock signals are fed through without change by default, so once you start mapping, you are adding or cutting fuel where required.  It has a neat trick with injectors - upto 50% larger injectors can be mapped automatically with a couple of clicks - fuel cutting to match the original fuel levels.  All the maps are additive - so adjustments made in any maps are all added together before being passed on to the injector/ignition.

You can also setup a staging rev limiter.

Latest is that you can now monitor knock signals as well - this wasn\'t working in the earlier firmware.

It\'s a lot more than a nice toy !

Is it a good replacement for PFC - time will tell - it\'s not as plug and play, but the interface is easy to use, and it\'s USB connector means it\'s modern laptop friendly.

Hi Prof,

Thanks for all your input. I am seriously considering this option i have found all the pieces excluding the  boomslang harness for a few sheckles over 500 (fingers crossed on no more bidders) that includes the ultimate a profec b and the gm 3 bar sensor.

[Prof]

You can find the boomslangs here - although I am not sure what wires they connect up.
 
I am going for mappable water injection and a possible 5th injector, so these harnesses are no good for me.

Thanks prof.
