ecu upgrade

[FknBuZZard]

Im in the neighbor hood to buy an ecu upgrade, but dont want to spend 500 bucks. i saw the z1 eprom chip for 100 bucks, is this a good chip? i have a 93 na. also i found a chip on ebay. called jwt chip for 34.00, i dont believe that jwt ebay chip is a jim wolf tech........or maybe it is? should i stay away from that? I found some decent threads on this topic, but im wanting to know whats the best chip to buy for a 93 n/a thats around 100 bucks or less. also found a website called http://www.gfchips.com they have a chip called gforce for 69.00. I just dont want to buy a really cheap chip if its going to do more harm then good, could someone steer me in the right direction, thanks

i think you should save your money and upgrade your suspension, etc.
trying to chip an na is a waste of money, imo.

AshSPEC, JWT, Z1, SZ, stick with these 4 and you're safe. I run a custom tune by e-mance "e-bay" chip but I've been in extensive contact with the guy and he's done multiple re-tunes for me, he is very knowledgeable but many don't like him because he started by selling copied jwt tunes on e-bay. also I don't believe its his day job I think he does it on the side so that's up to you to decide, other than that the 4 others I mentioned should do you well.

why must you give me negative answers... suspension, and headers are on the way, right now i got pop charger intake and 5zigen exhaust. wanting to put a chip on it on it after the suspension and headers are installed. even if the chip only gives me 6 hp ill be fine with that

I have a chipped Jim Wolf ecu for a auto(but will work with manual)na for sale. Its for the 1993-1995 models and itself is a chipped 95 ecu so you wont have to do the chipping yourself. Let me know

The main gain for a chipped NA in my experience is mostly throttle response though it does remove top speed governor, it raised rpm limit and maybe a very minor power increase.

[FknBuZZard]

thanks for info no limit

[NolimitZ32]

NP man.

[FknBuZZard]

not really a negative answer, not much power you can get out of an na, just like the vq engines.

Im trying to get 220whp out of my na

He's only trying to help. The cost vs reward on an ECU mod for an NA is minimal. He may sound more negative, but he was only trying to help. As long as you're only expecting 6HP, you'll be good

Ok guys im new to nico club but NOT a newbie to the 300z. the other day i came accross a denan ecu for a na z32. personally i know nothing about this brand and from what i can find the company quit making ecus for the z and the reviews ( what few i can find) are mixed. does anyone have any info, specs, or personal experience with this ecu? i would appreciate any info if possible

I'd pass, never heard of it. I'd go with one from a Z specialist.

[NolimitZ32]

WELCOME fellow TEXAN. as TDogg said, you are better off going with something from Ash, JWT, or Z1 due to their experience and continued support of their products. Not sure if SZ puts out any OTS tunes but check.

[BigTDogg (MA)]

They do, for $100 for just the EPROM.

And here's a free fish for the pneubie

well i have pretty mutch came to the same conclusion myself. ive searched for the past 3 weeks now and still have no more info on this ECU than before i started. i have owned and built 4 300Zs so far and i am now on my 5th. i have allways been a long standing customer with Z1 and have allways trusted their parts and i guess i will continue to do so. just thought i might try something different this time but......i guess not. thanx guys, and if you need a hand with anything dont hesitate to msg me. the newbie might supprise u. lol thx again

I put the Ashspec ECU in my NA Z32 earlier this year. You wont exactly notice a big power difference per say, but throttle response and overall engine "peppiness" is night and day between the Ashspec and the stock ECU. The removed top speed limiter and 7,400rpm limit is a nice addition as well. With my mods I'll be happy right where its at, as long as I can keep pulling on my friends 2002 WRX and my other friends 1997 BMW M3

[NolimitZ32]

No offense but either your buddy can't drive worth a sheit or his WRX is actually a 2.5rs because there is no way a NA Z32 (even honad's) should be even keeping up with a stock GD WRX, I know I've owned both.

[Chattzx]

Nope its a WRX and I know for a fact that mine pulls harder, I have driven both as well. His pulls harder in 1st gear once the turbo kicks in but I can always reel him back in after 2nd/3rd gear. His only has intake and exhaust so I'm sure if he did more power mods it would be more difficult to beat him. And for my friends M3 we are just about dead even, although his is a bit more rev happy with its inline motor.

[NolimitZ32]

Keeping with the M3 I could believe (E36) the WRX I just cant, he must be loosing compression or his turbo is going out, its just impossible, I owned a WRX for 3 years (took it from 100% stock to a 300WHP STI setup w/ mods) and have driven more Subarus of all kinds than I can count and I guarantee you a stock good condition 2.0L WRX is much faster than a NA Z32.

2002 WRX
0-60 = 5.4sec
1/4 mile = 14.7sec

Z32 300ZX NA
0-60 = 7.0sec
1/4 mile = 15.5sec

[Chattzx]

His car is in pretty good condition, maybe his turbo is on its last leg, I don't know. It doesn't smoke or make any noise, but like I said my NA has just about everything you can do power/suspension wise whereas his is mostly stock power wise with the exception of intake and exhaust. I'd probably need to drive another WRX to form a solid opinion on the condition of his. People do say my NA pulls harder than others they have been in though.

[BigTDogg (MA)]

You could have excellent compression, and a really strong engine. And unless the WRX is an auto, he can't drive either.

*disclaimer = Keep tests on the track though.

I agree with you 100% on keeping it at the track. We only did a little pull here and there (no crazy 100+mph speeds) and it was really late at night with no cars around. I think its a combo of having a healthy VG motor and maybe he isn't as good of a driver as me. I'd really have to drive his car to the limits to see its pros and cons to the Z. I sure do love the AWD system on those cars though

[NolimitZ32]

AWD is infact lots of fun and very good on all surfaces but I just love RWD too much.
