Hi,

I am thinking of adding a Unichip to my XR8 and I was wondering what type of performance upgrade it has made and has it effected the fuel economy of the car.

I have had a quote of $1150.00 from
Croydon Auto Sports at Silverwater and they claim a improvement of 15Kw improvement at the wheels.

Regards,

Peter.

Hi Peter,

I am getting a UniChip in my XR8 in the next 3 weeks. I will put the dyno results up here.

I am getting mine done through Croydon Autosports, and they have said I should get a minimum 15Kw increase (possibly more cos the chip will be programmed to suit the mod's I already have)

:)

Hi Guys,

know a customer at work. mate Joe built up this car. Fairmont Ghia EL. It has 70MAF, 65mm Throttle, extractors and a Unichip. This is a VERY nice car to drive! Its only series 1. Like to see it with a better uppe rand lower manifold.

I'd say you guys will see about a 7-9kW difference, but makes the engine rev so much easier.

Hi all,

Ok I don't have an 8, but I will share my experience with my XR6. I got the Unichip done on my XR6 3 weeks ago. I had it tuned on
Standard Premium Unleaded and not Optimax, because I don't always have access to a Shell station when driving. According to Croydon Auto Sports Dyno, Peak Power increased from 124Kw at the back wheels to 132kw ( a jump of 8kw)(The car has a full Herrod Motorsport Exhaust and Crow cam) However, this doesn't tell the full story...at the low end and top end the power difference was as high as 15kw at the back wheels..which is very noticeable under kick down acceleration conditions. However, better than this is the fact that I now get around 35Km more per tank.

ps: Its interesting to note that C&Vs dyno recorded my car as having 129Kw at the back wheels prior to the Unichip, whilst Croydon Auto Sports recorded 124Kw at the back wheels prior to the unichip. Both dyno curves were however the same in shape...Hmmm

I am looking at this option and was going to ring in the next couple of days for a quote. I take it UNI CHIP is the way to go?

Is the following statement correct:
" An engine management chip, like Unichip is only as good as the bloke with the PC doing the install"
Comments?!!!

Kelly and Alex,

I would be very interested in the results of the Unichip. Kelly, are you going to have a dyno before and after the Unichip?

I also had a quote from Croydon Autosports, but I would like to know if the power is reliable,drivable and how it effects the fuel economy. They told me that the economy would be improved from standard engine management system, with a 15Kw improvement at the back wheels or 19.5Kws at the crank.

Let me know how you get on!

Peter.

Hi,

Yeah - I am getting the car Dynoed before and after the chip. I am really interested to find out how much power I have with the existing mods.

I have also been keeping a track of my Km's/litre over the last couple of week's to see if there is any increase, or decrease in economy after the chip (although getting 723Km's out of one tank on the trip up from Melbourne will sorta throw my figures off.)

:)

Kelly,

That's great, this is the only real way to find out if the Unichip is worth the money. Could you please keep me informed on the outcomes. If it works for you I will get one also. Thanks

Peter.

Kelly,

I forgot to ask you what model is your XR8. As Unichip, at their website (www.airpowersystems.com.au) list dyno readings for both the distributor model and the sold state ignition model eg; AU's. This is a good site for information on the product, but it looks like it could be a pretty good thing!

ps. I have the EL II model.

Hi pmurgatroyd46

When you say readings for both the distributor model and the sold state ignition model eg; AU's. whats the diff between ef/el/el2 and the au? the ignition.


ps. I have the EL II model as well


Thanks Matt

Kelly,

The AU was the first of the Ford V8's to use a solid state ignition system. Ours have a rotary electronic distributor system. The difference (AU) is there are no moving parts (no wear) to distribute the ignition spark to the spark plugs. This system has been used on outboard motors and high performance motor cycles for years. The advantage of this system is a better, more consistant spark at high revs as the spark is generated by a energy pack and not a electronic spark jumping across a points gap.

It will not effect the Unichip in anyway or the performance, it's just that Unichip on their website: www.airpowersystems.com.au have two listings.

Anyway that is good for me as your car is the same as mine. Can't wait to see how you go with the chip. Bye!

Peter.

Hi pmurgatroyd46

I'm not getting a UniChip for my car.
But would like to get a solid state ignition system for it.I'm going to finish off the exhaust and some little things before getting it chip.As my brother is a software nut I have ask him to write me a chip.

Matt

The following pics are scanned images of before and after the UniChip installation on my AUII XR8. The only mods were a twin 2.5" stainless system with Hi-flow cats and Pacemakers headers.

Gotta say that the Unichip's most noticable improvement when driving is that I now seem to have better acceleration at low revs, which is great for normal driving. Don't get me wrong you do notice the extra hp up top. :)

I have been doing the research for my Au on this topic. There are two chips as already state one is a the other c and they are for the different ignition set up. The advice from APS is that the distributer type chip is not for use with solid state ignition as the signal from the crank is different, or something like that. That is the reason for the two chips.

We have a fellow up here in Brissie called Bob Romano who runs a shop called Bob Romano Performance motors (strangly enough :).

It is the only performance shop I know up here who specialise in modifying late model Falcons properly. There are a couple of others, Brock Shop (would u believe!) that claim to be able to do Ford V8 mods, but I've heard a couple of nasty stories about them. He is also a authorised UniChip, CAPA and APS reseller/installer.

Basically he is the Herrod's of Brisbane.
