Just get the shitbox back on the road first! You got $1500 bucks worth of repairs before you can even go buy a pack of smokes... *cough* tyres *cough* alternator *cough* subframe!

I was advised against the Greddy by several different tuners (most of which were only quoteing to do tuning (not supply the unit) and were all qualified to tune them...)

Apparently you get what you pay for, but im very happy with my Microtec LT-10. Will only stall once a month or so. Barely even notice it doing its thing... and everyone will tune them... and tune them better aparently...
Worked out about $2500 from my tuner for:
Microtec LT10 ECU
Tuning (3 seperate tunes)
Fixing some wiring
Supply and fit Walbro fuel pump

Not too bad i spose... Nice guy and would go to him again...

just copying redlines set up

Ah... righto then... same mechanic and tuner??

nah he lives in the carribean... just seems like he has no dramas with his turbo set up so i thought i would base mine around his

FtoSam · Post by **FtoSam** » Fri May 04, 2007 1:01 pm

I had very little dramas with mine as well... Only ones i had were errors on behalf of my dodge arse mechanic and now engine problems..
I think the biggest thing is the engine being able to handle it...
Would heavily consider a rebuild at the same time...
Other wise you could end up with a smokey engine...
Or if you dont have a vented catch can, you could loose your dipstick and have a messy engine bay...

My engine only has around 80-90,000kms on it and has recieved tip top treatment ever since i had it put in... and it still only lasted a month or so on 5 psi before ring probs...

Reco the engine... can only be a good thing....
PS. yours GPX or GR?

mine is a GPX... sh*t only last 1 month :s on 5psi... your scarying me away from turboing cos i sure as hell dont want to do a rebuild

the TUNE is the most critial part of this process. If its sh*t, too lean, has too much ping etc your engine will not last long.

yeah ive rang around and theres a lack of tuners... or should i say none... willing to tune a turbo'd fto with ANY ecu

Croydon will do it. My guys in Vic will.

Just run an emanage and its not that hard. To lazy tuning RB25s with PFCs.

I could tune the emange, its not that hard to get an OK tune but I wouldnt trust mine.

Who've you spoken to so far? There's that many tuners around here I'm sure there's one out there who will do it.

jonowong · Post by **jonowong** » Mon May 07, 2007 10:13 pm

ive tried uas they said they dont deal with that kinda stuff
bel just said a straight no...
mrt dude said he'll give me a call back once they ask the tuner...
advan said it would be a headache and hes reluctant to do it

kid_dynamite · Post by **kid_dynamite** » Mon May 07, 2007 10:30 pm

Croydon
Unigroup
JEM
Hitman
SAS
Dynodave
Haak
C&V
Hills Motorsport

Seriously theres a bucketload more. Kinda hard to quote someone on tuning without seeing the car first though remember.

khunjeng · Post by **khunjeng** » Mon May 07, 2007 11:14 pm

Yeah dunno who u have been talking to.

Most tuners will be down with it as they know its not that hard using a piggy back style system.

U might be talking to mechanics, not tuners. Usually a good tune house will do it all.

Most places will jump at the thought of custom work cos it equals dollars and is more intresting.

lols i might take you up on that offer...

do u have the software and cable?

the tuners will have the software u dont need to come down here as per KDs post.

Piggybacks, emanage, safc are easy to tune. anyone who says they cant is lazy or full of sh*t. If they can tune a PFC or Microtech than can any of these easily.I have looked at the map software and is pretty easy to follow.

Word of advice. fine a good place and get it done there. Dont bother doing any research until u have found a good place and BTW they willl tell u what to do anyway. Once u really get into the turbo setups...its quite complicated.

Ask KD he knows.

It's not so much being able to tune a piggyback KJ, I reckon one problem is that not all tuners will have access to the Support Tool software needed to tune the emanage. I don't reckon it's half as widely used as something like the Apexi S-AFC (which doesn't have the features of the emanage, but it can be tuned off the unit which is one reason they are so popular).

Jono you'll just have to do the call around and if they can tune an emanage.. I do know that CRD have it though. If you have any problems finding a tuner let me know and I'll get you some more names.

that destroys the DIY!!!

anyway heres some info on the turbo im using

FTO running on 4psi
(4psi + 14.7psi)/14.7psi = p/r (pressure ratio)
18.7psi/14.7psi = p/r (pressure ratio)
1.272 = p/r (pressure ratio)

pressure at the compressor outlet (Pco)
Pco = 4psi +1psi + 14.7psi (fto running 4psi with 1psi pressure drop from intercooler)
Pco = 19.7psi

after density after intercooler (Di)
Di = (Boost + Atmospheric Pressure) / (R*12*(460 + Post Intercooler Temp))
Di = (4psi + 14.7psi) / (53.3*12*(460+130Â°F))
Di = (18.7psi) / (53.3*12*(590R))
Di = (18.7psi) / (377,364)
Di = 4.95542 x 10-5 pounds per cubic inch

mass flow, fto at 8000rpm
ve = volumetric efficiency
Mf = (Di * Displacement in cu. in. * rpm) / (2 * VE)
Mf = (4.95542 x 10-5 * 122 * 8000) / (2 * 0.

Mf = (38.36497) / (1.6)
Mf = 30.2281 lb/min

corrected mass flow
CMf = (Mf * (square root of (compressor inlet temp in R / 545R))) / (atmospheric pressure / compressor inlet pressure)
CMf = (30.2281 * (sqrt (545R/545R))) / (14.7psi / 13.95psi (due to pressure drop of air filter))
CMf = (30.2281 * (1)) / (1.054)
CMf = 28.6794 lb/min

and the TD04L will be out of efficiency before i even know it
