help with tune

[motoboy]

hi all wel im on the south coast and am after a good tune for my car 1994 gsr 4g93 as it is tuned verry rich! it gets 20L per 100kms where is a good spot in sydney to get a dyno tune? i was thinking of auto tech engineering?
also what price am i looking at i want to spend about $500
or would i be better getting a chip?
also what power would i make with good tune?
i have
external waist gate
ported exhaust manofold
4g63 tb

Dan, where abouts on the south coast? also what ecu are you running?

^Nowra Sean...Standard Ecu. Its Aarons old car.

What ECU do you have in your car? if its an untouched standard 1 then you cant really tune it much at all

Give Meek automotive a call, they can chip the standard ECU and throw a tune in it for a cheap price

Otherwise you will need to get an aftermarket ecu for around 1k and a tune will cost minimum $600

Autotech charges minimum a starting price of $800 from memory

Power wise i would say between 110-130kw at all 4 wheels

Ahuh! I see... Well if it's only standard, I'd be looking at what may cause it to run THAT rich, Oxygen Sensor failed? Boost leaks?

 

[EVOCPE]

Standard ECUs run rich as they are, i was running on my stock setup, idling around 12AFR and 10 on boost sometimes even see a 9 off the wideband

if o2 sensor is ok, it should always run at 14.7 for idle and cruise. when i put the ecmlink in i realized the 02 sensor wasnt working at all. it was running open loop all the time.

you could always buy a wideband and check it yourself. it will cost as much as getting someone to look at it

mine has a brand spankin new one and the back end of my coupe is blacker than an rb powered silvia. it no myth 93's run rich.

heres a photo of my head prior to rebuild. cylinder 4 show extensive carbon builup from running very very rich

all 4 pistons showed similar carbon levels.

i did have a meek chip, but i didnt think it was rich. it was getting 7l per 100km on the freeway

Think of the comp you gained from all that carbon build up on the pistons... LOL

 

[EVOCPE]

Meeks chips are all installed with a better tune than standard, and theres a HUGE difference between how both of the ECUs performs

I had an ECU here that was chipped and had a tune in it, i felt that the OEM tune seems to hit boost quicker and pull u back, while the tuned ECU i had here had a nice and smooth linear feeling

Plus the fact that i was hitting 10.0 AFR on the standard ECU on 16PSI and around 11.8 AFR on same boost with the chipped ECU

Something is very wrong for 20L/100kms, more than just an o2 sensor. Id sort it out before you tried to mask it up with a tune. Check that they are gsr injectors and not evo 510cc that have been swapped in.
