i will try , are the greddy e-manage ultimate eezee or hard to install and tune self ?

 

350zQ8, dude GReddy E-Manage is hard to tune if your new to this thingy, i got OBDII Scanner if you need i can help also, i have similar problems happening to my car right now i`ve lost power about 25 whp dynoed in the same dyno as yours at Modular Performance, i can put my MAF in your car then we dyno to see what happens, just tell me if your car is 2005+ i would highly recommend you Cypher, because it will read the factory Wide Band O2 sensor, so you will check your car by your laptop

PM me with your number if you need any help

this is my OBD :

 

William Unfortunately he got JDM Spec so he can`t reflash, what about GReddy E-Manage Ultimate it will work with his ECU ? i mean it will work with US/JDM Spec ? or only on US.

 

I believe EU is universal for all vehicles, regardless of being JDM or USDM.

 

Thanks for conforming scareface

What about UTEC ? i guess this baby is for USDM only

 

hey hey guys, thats normal. its a full bolt on without tuning. and this is not the first car to have the same A/F.

the stock A/F is 10. somthing, if u add plenum and stuf like that it will be lean. ur geting more air to the engine. do u think bolt on will add fuel ??? :P

with intake and plenum ur A/F shuld be around 12.7 to 13 so what if u have all that stuff on ur car with out tuning. ?????

get u a utec.

 

i can do this for u, if u need to install the e-manage on ur car, all so i can do the ultimate and if u need to open ur speed i ll do it

dont wory about tuning it i have every thing base maps turbo maps, i can make for u a map, just give me a call

ahmed

 

i have all the spec, for JDM and US.

i have tune my car with the blue e-manage and i got 479 whp 11 psi

allso i tuned my friends car his name is omran and i give him a 406 whp with just 7.5 psi A/F was 11.7
for more info go to the second dyno (jasem) ask him about ahmed snayen car and omran car.

 

utec will work just fine with JDM. we allready did this for a car my friend

take it easy

u can do any thing with the JDM spec,

allso i have utec maps

 

i talk to you brfore , you tell me you take about $520 for the installation,

 

Im sure your car is fine, i bet the sniffer on the wideband messed up....no tune....with boltons you really dont need a tune, only a tune to make those bolt ons work right, but those shouldnt lean a car out. Get a wideband, and i bet your AF is safe, plsu NA z's a lean anways

 

i know for a fact that jus bolting on stuff will no make the car run lean. like the one guy said you dont need a tune with bolt on's. ive seen and run stock G's and Z's to watch the stock A/F at about 5K its goes right to 11 to 1 and slightly closes the throttle plate. before 5k its still rich high 11's to low 12's this is stock. bolt ons are not going to change this unless the MAF is not reading the right amount of air coming into the motor. bolts ons are only going to flow air better in and out of the motor and no bypass and provide more air to the motor. that maf is not reading right or u have intake leak. or i bet that wide band was on the way out. ive toasted many wide bands. and thats how they go, they start reading lean. and so do MAF's when its going bad too. so i suggest put the stock intake on and retest. if the a/f looks better than your intake is make the MAF read wrong. or if it doesnt read any different the that a/f is going bad. someones sensor is going out. the MAF reading wrong and is bad or the wide band is going bad.

 

DUDE!!!! i just looked at those print outs the air fuel alpha is WAY!!!! lean that MAF is going bad or u have a intake leak that wide band was right. i dont know baout 17 to 1 though. but if your anything above 105% air fuel alpha u have something going wrong like that maf is probably the problem since u didnt say u had a rough running motor at cold start up. it is the MAF!!!
