Hey all--would you all mind giving me your input on whether I need a tune for my g35 revup w/ the following mods: Mrev2, 5/16 spacer, nismo headers, amuse titanium intake pipe w/ nismo drop in filter, HR y pipe.

 

u dont need one, but if u want 2 extract more power from it, then i suggest u do. get either an AAM or technosquare reflash, unless u plan on doing alot more heavy motor work, such as turbo's, then get a utec and go from there.

 

yes def. get a tune. your gonna need one to get all the power you can

 

to utilize the the MREv2 and Spacer, i would do the reflash. the only other thing that would alter AFR now would be a set of test pipes or high flow cats but only slightly leaner.. From the looks from your mod list, looks like you're keeping the stockers since you would have changed it out after your headers and your Y pipe.

remember is not all about the power gains a reflash will do, its the driveability improvements!

 

Thax guys. I'm definetly looking into a reflash--and I am leaning towards technosquare. But had some q's:

1. Is the reflash different for the revup engines? (I though revup redline was 7200--does this mean that the redline would be decreased to 7100?).

2. I live in the midwest w/ 93 octane premium gas--will this adverselly affect a reflash by TS in CA, where 91 octane is used for premium?

3. Is it recommended to purchase an additional ecu w/ original stock data on it?

4. Will the TS reflash addversely affect any of the stock functions?

5. Will the reflash, will this put extra strain on the engine internals (as a result of opening up the valves at wot?

6. Can I request that TS reflash my ecu specifically to my particular mods?

7. What is everyone's esxpereince w/ TS when sending in and getting their ecu reflashed?

 

Yes. the reflash is different for the REVUP engines compared to the nonRevup. the new Redline for the REVUP engines is high 7000s, not 7100 as it is for the NonRevups.

NO. Technosquare Programs EACH AND EVERY ECU to the owner's specifications. If you state that 93 octane is used, they reprogram the ECU to be adapatble to 93 octane. If you plan on using race gas only, the program will be done with race gas in mind, etc.


No. There is no need to purchase another ECU.

all "Stock functions are retained" if you mean stock functions as in traction control, abs, radio, security, etc. those are all left alone.


The only extra strain is what you will be doing with it now that the car is 'opened up.' example: if you drive normally like you did before, your engine is just now running more efficiently.... however owners after finding out the cool changes tend to beat on the car more i.e. prolonging shift points, more WOT, but your car can handle it. trust me.

ALL FSPEC (Full Spec) ecu flashes are custom programed to your particular mod list or any request that you want. i.e. even higher redline than normal reflashes.. The user obviously assumes the responsibility of their actions and requests. I.e. technosquare is not liable if you blow your motor cuz you wanted an 8000 redline and they did it for you.

That you'll need to use the Search Button for. As for the logistics of the process:

Typically the best way is send the ecu FedEx for next day delivery by 10am. The day your ecu is received, it is flashed and sent out. You pick the return delivery method, so if u want it sooner, Next Day air by 8am or whatever.

any all questions can be answered by the staff at Technosquare. 310-787-0847..

hope that helps.

^^Thanks Cheston--Your responses are very helpful!!!! Some additional q's if you don't mind:

1. What would you recommend I request for a redline on my revup if I do not want to blow my motor, but want something higher than stock?

2. I assume having a ecu reflash will void the powertrain/engine warranty?

 

The ECU reflash typically will add 500 rpms to the stock redline. It's when people want to go beyond that additional 500rpm range. It's because some cars make more power throughout the rpm band due to cams or what not.
i think the stock redline on the revups is what, 7100? so you can to 7600 safely.

With that, you will only void your engine warranty if you get caught. Dealer will have no idea you have been reflashed, even with a plug in of the CONSULT2... so as long as you don't shoot yourself in the foot at the dealership by telling them, you're golden.

 

It was verified by TS that the redline for revups is 7500 and they can tune for 93 gas and for my specific mods. But I was told, that after install, the relfash could cause thrown cels? Anyone experience throw engine codes and lights after having their ecu reflashed?

 

depends, some customers said that after the put in the ECU for the very first time , the CEL comes on, we usually do a scan tool reset (a la CONSULTII or SnapOnTool Diagnostics tool to reset it..) there also happens to be an ECU reset procedure via key and gas pedal, instructions posted on Technosquare's website.. and the CEL usually goes away and never comes back again..

another precaution is if the CEL does come back, we usually track it down to problems the car had originally.. i.e. test pipes, or leak from plenum, or something else. its rarely the fault of the ECU reflash.

 

I got AAM's ECU flash a few months ago...fast turn-around, good customer service, and perfect performance gain. (raised RPM limit, removed top speed govenor, AF's perfect after flash). I saw solid gains throughout my RPM range.

*search my SN...i did a full write-up about it.

 

Is inceasing the redline on revups to 7500 safe for all engine internals at WOT?

 

If it makes any diff i sent my 03 ecu out to technosquare on thursday morning for the l-spec flash. i'll let you know the results if i get the ecu back and make it to the strip on wednesday!

 

Non-Revup engines limits at ~ 7600rpm sustained
Revup engines limits are ~ 8000rpm sustained

there is nothing to worry about. Honestly speaking, if the ECU reflash was detrimental to the car, they would not even offer it.. it is perfectly safe for your engine, tranny whatever--its what you do with the car after you get the ECU flash is what makes or breaks the car.


(same deal if you get any aftermarket part installed.... if you abuse the car beyond the limits of the car itself, it's the user's fault: not the aftermarket part)

 

Thanks for your explanation and reassurance I'll be placing my order w/ technosquare shortly..

 

can i get a reflash done while i wait?

 

Yes. Road tune typically takes less than an hour

Dyno tune is around an hour or so..

 

Is there a big variation in prices(ranges?) for new ECUs and are there many options as in types?

 

I'm trying to decide on which way to go. TS reflash or UTEC. Talked to Ted at the Stillen Open House and he recommended TS but the UTEC seems more versatile especially since you can have different map settings for different situations.See my mods in my sig and the only other thing I may add before deciding is HFCs.
