Is this a limited time offer?

[WDRacing]

Can you do specific tunes Alan? Or are you just buying in bulk for a cheaper price.

Call and see if they have gotten to it ... have you paid already?

It might not be too late?

JWT can tune pretty much anything to my knowledge... but obviously for something wild you are gonna want a standalone tune anyways.

[S14tat]

they got my ecu already and they already flow tested my sard 550cc injectors. so i'm afraid its too late.

s14tathow long did they say it would take them to get the ecu back to u. Im goin on my 5th week of waiting.~Sam

[S14tat]

they said it would take 2 weeks to write the program. so i guess it takes around 3 days to get to them, + 2 weeks, and anotehr 4 days to get back on ground.

so thats around 3 weeks. why not give Ben from JWT a call and give him your quote number. they'll tell you whats goin on. also if they had a problem, they would call you.

they called me today saying that they couldn't get the SARD injectors to fit. i should've sent them the collars that goes with them.... doh~!

[hannibal]

Kinda off topic, but you sent them the actual injectors you plan to use?They write their programs that precisely?!? I thought you just TELL them what your setup is, and they write a generic program to match.

How would this work if you purchase an ECU from SPL? Are these premade programs or do you send the ECU and injectors to JWT?

It may actually be worth it for some people to pay the extra bucks to get a true 'custom' tuned ECU.

Ive been thinking about management a lot lately. That seems to be the key to making good numbers. Its Emanage vs JWT right now. For $485, the JWT looks even better.

I'm very sorry , but I have to inform my fellow nico friends. JWT cannot tune side feeders over 740cc. Well not yet anyway. So if you want to run 850's your going to need stand alone. You see I bought a set of Tomei 740cc injectors for my KA ( thinking to the future mind you). Well Jwt said they never tuned that actual injector , so Ben told me to send "one" injector up with my ecu to flow test it to make a perfect fuel map. Turns out the Tomei 740cc injector actually flows 750cc+. Good thing thing they tested it or I'd have one rich running KA. "No problem" Ben said , "we'll have it tuned for you in about 4 to 6 weeks because we're a little busy". No big deal. I can wait. Problem is that was June 9. I call every two weeks and get the same answer '' we'll get right on it , priority #1 , it'll be done by next week" I still haven't got my ecu back yet.

We just got back a customers ECU that was tuned for 740's?

Typically all injectors are within a range, not all 740 injectors (regardless of make) flow 740, you'll have some that are 750, some that are 730, etc. This is why more expensive engine management such as the Motec M600 have individual fuel trims per cylinder.

Basically if your car calls for anything larger than a 740 or 72# injector you need full engine management, this is plain and simple. The level of tune required for that high of cylinder pressures to prevent detonation at the same time producing peak numbers is more than JWT can offer. Like I said before... as long as what you are building is within the norm (ie. 370 - 740, Z MAF, etc.) then you can easily run a JWT ECU, but anything exotic (ie. 850 - 1000cc injectors, MAP, etc. ) obviously needs more than the JWT can do.

[S14tat]

yeah they said that they never wrote a program for SARD injectors yet. so they needed to flow test it to see the how long the injector stays open for, the spray patter etc. lets hope they can finish it on the promised date.

That is fine and dandy coming from you. But I really wish JWT said not only that but also " We're sorry Mr. D-unit but we CANNOT TUNE YOUR ECU w/ your specified injectors". Then I can work on a solution. Not " we're still working on it , it'll be done next week. Priority #1" It will be 6 months of that on Dec. 9.

Good thing I sourced a stock ecu , or my car would've been down for a long time. Imagine a customer of yours in my situation. It sucks because I wasn't charged yet , so I really can't say anything. Just tell me you can't do it. Come on JWT , I have over $3000 of turbo parts sitting in my room and no ecu to run them. Besides , I really really miss my no speed cut. the stock 112mph fuel cut suxx b@!!s.
