Ecu tuning

[jab11185]

is it really worth sending your Ecu away for someone to take off the speed and rpm gov? or should i not even bother...

i do plan on going turbo this summer and wasn't sure how a tuned Ecu would contribute if at all...what are the pros and cons?

[silkk]

send your ecu to JWT. i heard they were good at tuning ecus

[jab11185]

i've heard that they were good at that too...i'm just not sure what they're doing to help the performance of the car other than taking away some limiters that i could get rid of by cutting a couple wires...

[marshun]

is that all youre taking off? and why? to me it sounds like its not worth it.

[Dattebayo]

Its definately not worth it unless you have something else to program it for anyway. No matter how much you program into the ecu your first time, it still costs the same. after that, you have to pay $100 for each reprogram. So might as well get all you need at once.

It'll also take forever if you send it to JWT..

Iner Circle via Phase 2 claims 15-20hp increase on NA KA's and more on SR's with their stage 1 ECU upgrade. Not on stock engines though, you pretty much have to already have full intake and exhaust. They not only remove your limiters but they redo your fuel maps on Sr's all they way up to 15lbs of boost (limit for the stock turbo). I talked to one of the guys who works at inner circle and he told me if I didn't feel a kick in the pants difference come back and talk to him. I am still saving up for it. BTW turnaround time is 1 week.

just sent my ecu off the JWT and a 2 month to get it back that suck but it is worth it .

what all mods u got? if your spraying on an all motor ka it isnt worth it to get the ecu upgrade @ all

[NX95240]

iam spraying it right now with 75 shot. but turbo it really soon. sc-61 with 69 trim . ross piston , pauter rods, arp , valve springs titanium retainers, jwt cams, 11 lbs flywheel, 72 lbs injectors, corba mass, HP cometic headgasket,etd mani when EVER i get it. that most of my stuff..

[crazy2002mexican]

sounds like a nice setup, ive got cai,header,2 1/2 inch exhaust (no cats) fidanza flywheel which im assuming thats what u mean by 11lbs and a spec stage one clutch with bfg drag radials....im gonna be spraying a 75 shot very very soon...i will prob do a 5.0 swap or a 4.6 once my motor blows im tired of only getting small gains so im going 2 a V-8

[Dattebayo]

you must be crazy if you wanna put in a 5.0 in your handling will go 2 crap. stick with O.E. stuff, man. We ALL dont have to be like Aries.

[240SXer]

I think when it's all said and done a V8 240 will cost about the same as a KA-T or SR for the same performance. I race modded mustangs all the time and smoke them. I'll grant the 240 is a lighter car, but to get any real power out of a V8 you've gotta go with crazy internals, supercharger, or nitrous. All are expencive (the nitrous isnt if you don't care about the motor lasting). But it is unique. It's not always about the cost. I only drag race so any handling concerns don't bother me. But if you care about handling V8 is a big no no

[crazy2002mexican]

@ this point i dont do any auto-xing so im not worried about handling and im not trying 2 copy aries. Have you seen the gains that cams, cam gears, pulleys, pistons, do to a V-8?? And PARTS ARE ALOT CHEAPER. Im just eventually going straight to the power source.

You have no idea what you are talking about. A properly tuned nitrous setup is no more dangerous than a turbo setup. In fact, the average person is more likely to wreck their motor by turboing it, than slapping on the bottle.

The problem with nitrous is the reoccuring cost. After you've installed and tuned the system, then run twenty bottles through it, you've pretty much covered the cost of a turbo kit.

[NX95240]

phax, i with you on what you have said. i have mine about 2 years and could have paid for a turbo kit now. but i had fun with it though.

I have no idea what i'm talking about? How much do you pay for a "properly tuned nitrous setup" on a V8? it's not cheap, and nitrous isnt cheap. If you want to go full direct port and do it right the cost of even setting up the nitrous is fairly high (let's not forget there are 8 cyls that need to be sprayed, not 4), then you add filling up the bottles and you're just as high as the turbo/supercharger. When is said the nitrous reliable thing, I was taking about just a big single fogger. That's not all that safe, but it IS cheap.

And about the "Have you seen the gains that cams, cam gears, pulleys, pistons, do to a V-8??"... Have you seen the cost? Including getting it installed? That's where I meantioned the "crazy internals" price by price dropping a V8 into a 240 you're not going to get a lot faster of a car than going KA-T or SR for the same price. If you're talking about dropping a fully built 350/supercharger and/or nitrous, you could easly shatter the potential of a 4cyl. But it won't come cheap, not even close.

Are we also consitering the cost of a V8 and getting it put into a 240 (custom mounts and such). You should be, becasue I am.

[Dattebayo]

alright boys. take it outside. dont hate, even if it's a dumb idea. My point is if you take a relatively lightweight car and stick a big a$$ engine in it, you WILL have more problems to compensate for. 240's are known for drifting and the multi-link suspension that it shares with its bigger brothers like the Z32 and Q45. If you put a 5.0 in a Q45, you would not have the suspension problems you would have if you dropped the same engine in a 240. But look at the total weight of the Q, front and back. In said 240, it would be notoriously hard to conrol a hard launch in the quarter mile, since thats what you are obviously going for.

[crazy2002mexican]

Yup Yup, "crazy internals"?? I have alot of friends that would be more than willing to help me out with this project. I have yet to pay for a mod to be installed on my 240. The most ive ever paid was either ordering pizza for my friends, or filling up somones gas tank. I will already have a nx nitrous kit set up for my 240 and who said any of these things come cheap? I know domestic parts are alot Cheaper though.....

[240SXer]

It would be cheaper if you had a 240 that had a V8 in it already. But with the cost of the motor, install, etc. you're going to pay a pretty penny. I'm assuming a good fairly new EFI V8 btw. To be a good overall "street car". I'm on the stock suspension and mine launches decently. It just wheelhops like crazy because my subframe spacer fell out. heheh

I get 1.9 60s with the Nitto DRs.

[crazy2002mexican]

that sucks on the wheel hop...1.9 or 1.8 is about what im expecting out of mine hopefully these g-forces will hold up till then. And as far as properly tuning a V-8 nitrous setup shouldnt cost to much @ all. My friends got to pull over 10 times and none of them paid over 100$$

[jab11185]

so ne way....if i do have an intake and full 2.5 inch exhaust it would help....and if i understood correctly i should put in the turbo b4 i get the ECU done..right?
