so basically i took the Z (2003 m6) to one of the "best" import tuners for all cars on the east coast. im talking about 1600whp supras, 1000whp evos yadda yadda. the guy who owns the supra is a good friend of the family so we figured his tuner would take good care of the Z even though she is slow. i had talked to the shop about possibly installing my cams and valve train which is a decently expensive job so i thought they would see this as a good opportunity. well needless to say they did a joke of a job. only did 7 total pulls tuning the car, tuned it on the maf voltage, and jacked maps from a cammed z(my z isnt cammed yet although all my parts are sitting and waiting for my tech to install them). the baseline was 240whp. all he got out of it was 247whp. for my mods that was REALLY low so i did some research and come to find he had jacked the maps and not tuned on a wideband. the tuner had the balls to tell me his DJ reads high!

i took the Z to the shop where my bf's ls2 gto gets work done. the tuner there, eli (who had never used utec before let alone tuned a z) showed me on hypertermial the sketchness of the first tune. the afr on the ond tune was 11 to 12 across the board, the new afr is around the 13-13.2 mark. eli redid my tune ( i only have the dyno from the first session, it got late so i came back the next week and he finished it off) and in conclusion got 270whp and 265tq in its final pulls. mind you all pulls where done in 4th gear on a dyno jet. eli's DJ is fair. it read an intake only 03 m6 z at 232/225 ten minutes after my run. eli's dyno was not corrected but i do beleive the first shop corrected his numbers. it is def a very different car after eli's tune and has pulled away from mid and low 13 sec cars on the streets. ill post up the final sheet if i can find it since i think i deleted it from my email and the dyno of the tomei cam tune (hopefully sometime by the end of the month).

I could be very wrong, but those AFR's are very high. Not to say its necessarily a problem, but I'd definitely log any detonations, as a bad bunch of gas could spell the end of your engine. I've never seen someone recommend going much above 12:1AFR.

all my buddys running tuned n/a set ups are running 12.8 to 13.2. have had no problems with rod knock or spark chatter. my goat runs that lean (13.5) as well. many untuned bolt on z's have leaner afr then 13.2.

 

[i8acobra]

Your AFR's are fine if you're running 93 octane. Out here in Vegas, we shoot for 12.7:1 on 91 octane. Just for information purposes, your dyno numbers are in fact corrected. They're SAE corrected.

 

[NoZYet]

My bad. Guess I was talking about something I didn't really know. Congrats, your numbers look good.

~Pat

 

[baby_ruiner]

the first set yes they are corrected, the second set im pretty sure they are not. thanks for the props guys...hopefully with the cams and valvetrain ill be able to take it to 7200 with good use

on a side note anyone have dynos or numbers from full bolton, cammed tuned nonrevups?

You would be correct on a forced induction motor. I usually shoot for 11.7:1. NA cars, I aim for 12.7:1.

Both dyno charts are corrected. The way to tell is to look in the upper right corner. The "CF: SAE", means your numbers are SAE corrected. That's the preferred correction factor.

thanks i miust have been thinking about the most recent one, im on my bf's a$$ about emailing it to me

 

[one_Quick_Z]

+1 on the numbers

 

[baby_ruiner]

thanks guys...i dropped my car off last night at my friends shop to install tomei 264 cams and jwt valve train. hopefully it will be done tommorow and ill have it on the dyno fri or sat to get tuned . ill post the final results up. there is lil info on n/a cam setups and i have found NO dynos whatsoever so should be good info for ppl heading that route

 

[chrisaray]

Can't wait for the results. I have Nismo cams sitting on my desk waiting to be installed.

 

[baby_ruiner]

will do! i have heard of 15 whp and up to 25whp...i dont know what to expect. anyone have any insight?

 

[baby_ruiner]

here is the the dyno from the tweeking of the first time. i have my cams in and put down 255/245 at the same dyno but i dont have that one yet. should be tuned next week

 

[chrisaray]

Nice! I have been trying to find the time to install my cams for a while now. Can't wait for the results. I'll post my dyno sheets as soon as they're in.

good luck. seems most ppl are afraid of it but it didnt take long and we didnt pull the motor, like some ppl told me they would have to do (Z1 in ga and forged i think).

that last dyno i posted was i/e/h/testpipes/spacer and tune.

i dynoed the car with all those mods plus cams WITH NO TUNE and it did 255/245. hopefully ill see a 20 plus hp gain of the tune since the afr is just as jacked as the first time it was untuned. should be sometime next week. keep your fingers crossed

You are thinking about Forced Inducted cars. I tuned turbocharged cars for around 11:0 - 11.5:1 afr.

My NA Z is tuned for 13:1- 13.5:1 on 94 octane.

tis true. when i was richer the car ran like crap. im thinking with cams in it it will want it a lil richer. any thoughts. i think icobra is around 11 ish.

Yep, you are going to have to add a little fuel up top. Which cams are you using?

You would still want to hover around 12.5:1 - 13.5:1 ... depending on your poison for an NA car.

im running tomei 264s with a 10.2 lift (about .410ish") well i really want to keep my tq which is around mid 260s before the cams. i have seen a few de's put down 280whp (full bolton no cams) with my same tq and always wondered what robbed me of the hp (my peak was 268 i think). when i put that cams in i did have to replace the spark plugs and some other misc parts (totaling almost a grand grr!) so i wonder if that robbed me some power as well. any ideas?

Those 264 Tomei's are good stuff. Would be my choice (or 272) for cams with the non revup VQ.

Your hp suffers up top because of the "normal" intake restrictions (plenum, etc) of the non revup. Those cams will CERTAINLY open that can of worms up.

Did you do a plenum spacer of some sorts? That helps the inbalance on the non revup.


I would imagine you'll top 280whp.. But, don't worry if you don't, it'll still pull like lightning with excellent throttle response. Dynos are just rollers that put out inaccurate numbers from dyno to dyno.. Don't put much stock in them. As long as you our happy that is all that matters. And that you have more power than before.. and can use it more often.


Did you touch the rear diff yet? LSD or 3.9 + R&P? THAT, with cams is fire... pure fire.
