Unichip ECU installed, excellent results. 194rwkws

[EnricoPalazzo]

Hey guys, as title suggests, I got my aftermarket ECU tuned today. WOW is all i can say, the difference in torque and power is unbelievable.

From lookin at the Graph, ive gained 20rwkws + in mid range over a number of spots, and a total of about 10rwkws in max power. This is all done using same boost level of 13psi.

On the road, the car is breaking traction in 2nd which it didnt used to do. Acceleration feels great and the seat of the pants feeling is definately more.

The car has been tuned to an excellent AFR of 12:1 and they put in about 10deg more base timing. The dyno was run in non-shootout mode, so i would assume that if it were shootout mode, the figure would be in the 200's .

So rounding things up, the car is alot more driveable, there is power increase everywhere and the power curve is alot more smoother which is nice.

I still have to get my ebc workin so that i can hold 1bar of boost. ATM the bleeder is getting to 15psi, then droppin to 13psi. I also have an adjustable cam gear exh side gettin here soon aswell as finishin installin my CAI and partition.

Current mods are Trust front pipe, 3inch exhaust, HKS pod, GTR intercooler, unichip, and bleeder set to 13psi. Also I have heatwrapped all piping under bonnet, and daim, those temperatures are now kept down. It wasnt even hot after a huge burn thru the hills

So in summary, I think the Unichip is very underrated. It was perfect for my needs, and I am very happy with it. :headspin:

price?

[strutto]

Stock turbo? By Trust front pipe do you mean the front pipe only or has the dump pipe also been changed??

You need to change your tagline too! Great result...

[EnricoPalazzo]

R31Nismoid: I bought the Unichip of ebay for $550. Tuning was $250.

Basically it was an absolute bargin. And SAFC II which would have cost more has not nearly as many functions, as Unichip can do somethin like 400 ign/fuel points.

Strutto: Im running a stock turbo, well it says nissan on the cover. By Front pipe, i mean after the stock dump, the pipe after that that connects to the cat.

[Guest RedLineGTR]

very good results. very good price too...

[Steve]

Congrats Dean, nice result. Did they say why were the runs done in 2nd gear? It wont effect the peak power figure anyways, and is still good for comparison as the first run was done in the same gear. $250 for a full tune is a good price too, wish power fc was that cheap:p

[Kinks]

nice

[Busky2k]

Nice work there dean! Your car should be absolutely hammering now!! The power looks alot smoother too!!

I gotta give you another run. Ive done a few more mods too

[benm]

Installing an Adjustable Ex Cam Gear is gonna easily crack the 200rwkw mark before you get it retuned. Im no expert but are your AFR's still all over the place alittle ? (I honestly have nfi with AFR's).

Have you got pineapples in the rear ?

Also if its the stock turbo how long do you plan on running 15psi thru it for ? :wassup:

[Busky2k]

IMO the AFRs are quite stable, especially at the top end, where it really matters. Down low it'll me more wiggly because most ECUs try to run closed loop still....

[sweetr33]

good results there championl. Will look into this idea for the meantime i think.

[EnricoPalazzo]

Steve: Id definately say dyno runs wer done in 3rd. Have a closer look at speeds.

Benm: The AFRs are really good. Looks like a consistent 12:1 which is optimal for a Turbo charged engine. Im actually running 13psi atm, but wanna run 15psi. I dont gun it much anyway. I still gotta do some more investigating into it thou. Also i have Tien HAs, no pineapples, but asky bushy2k, i have no trouble launchin hard

Bushy2k: Bring it on bro, I still got some more things to put on, so the car will be quicker. It does feel alot quicker. Heaps more torque.

[Ronin]

Where did you get it tuned? Are these available for 32's?

[MJ]

Thats a great power figure there for the mods uve done

my mods are pretty much the same as yours im getting it all tuned soon i cant wait for the dyno sheet

[Black33]

whose dyno was this on.............................unichips??

(only stirring)

[Guest Robo's]

Excelent numbers mate.

Dont worry about pineapples, ive got stiff Tein NA's, and done a PB of 1.94 for 60 footers and plenty in the 2.0 area with a 13.3 1/4, with a similar setup to you, without the FMIC.

[whatsisname]

I was always very impressed by my Unichip (when I had it) It's only when the stock ECU reaches its limitations does the Unichip become an issue. At the time (3yrs ago) no Unichip agent (including APS) could confirm for me that the Unichip/stock ECU combo could work via a Z32 AFM? At ~225rwkw the Unichip could no longer prevent massive timing reduction via the stock ECU sensing a seriously maxed out AFM voltage! It was for this reason (& a few others) that I removed my Unichip & went for a fully programmable ECU.

Dean you may find your car doesn't display the same characteristics as mine did (I also had a much larger turbo & cam gear adjustment at the time) but as airflow gets higher, via improved breathing, your AFM will reach the same point mine did. Your stock ECU will be the deciding factor. Mine pulled 15' timing out 3x in one power run. This resulted in a peak of ~225rwkw with a number of 15-30rwkw dips, & a pig of a car to drive Think, 'good ol' R33 flatspot,' & then you'll know what I mean.

If someone has successfully got a Z32 AFM to work with the stock ECU (don't see why not) then you'll have no problems

EDIT: Just had a good look at the dyno sheet mate. Firstly, congrats on the power. Second, your before & after power curves are the same as mine were! I asked Turbo Tune at the time (only real option for tuning Unichip in SA - unless you head to Port Augusta) if they could do a Z32-stock ECU set-up, they weren't sure but would give it a go! I didn't bother. Ask TT why they couldn't completely get the rid of the small dips in your power curve? I'll be interested to see the answer.

[GTS-t VSPEC]

Nice result.

Just a couple question though.

1. Why was the run done in 3rd and not 4th?

2. Why wasn't the run done in Shootout mode?

3. One of the dips in your power curve should be the NVCS, what is the other due to?

Cheers

Paul

[dojobi]

Paul, when I had my car dyno'd, they told me they had to do it in 3rd or they'd hit the speed limiter. Also, isn't shootout mode really just there for comparisons? If you're just after a tuned car then why would they put it in that mode? I know I personally would like it tuned in shootout mode so I could compare, but some tuners just don't care about that, they just care about the before/after.

[EnricoPalazzo]

Dynos cant be compared, even if it shootout mode.

Speed limiter is now removed via unichip.

Will post more later
