Hey guys, looking to get an SSIM in the next few days. Currently, I have the GAB mod, OBX headers, custom 2.5" exhaust, VIAS block-off plate and a tune with a VAFC. Would it be bad to put the SSIM on the car with the current setup that's tuned for a regular IM? If it matters, my VAFC is set to take out 1% fuel after 4k and 2% fuel after 5k. Will the SSIM make it run lean? I will also be using the VIAS plate on the SSIM. Really would love to know ASAP please. Thanks!

 

I think you'd need the Technosquare reflash that raises the rev limiter to take full advantage of the SSIM.

 

Rev limit aside, can't he adjust for the SSIM with his VAFC?

 

I am pretty sure he will have to re-tune. But as Scott said, without a rev limit increase there really isn't any point

 

Well, I do plan to get a UTEC in the future because I want to run nitrous. My car really isn't making power beyond 6500 anyway so would it be beneficial to throw it on there now?

Also, I do want to run nitrous, but couldn't I have Technosquare extend the rev limit, flash it, but just tell them to leave timing at 15 degrees?

 

Nitrous would have to come 1st.
TS does not mess with base timing, if that's what you're referring to.

 

Are you suggesting he gets nitrous before the UTEC? That makes no sense.

IMO I wouldn't run nitrous unless you have proper safety measures on the kit (window switch, TPS switch at minimum), and a wideband 02 sensor. Beyond a 75 shot you will need to be able to adjust timing (utec).

Personally I'd say don't touch the SSIM unless you go with a TS reflash or UTEC. Even then, you'd want more aggressive CVTC timing and that's only achievable with either a 500 dollar greddy V-manage or getting a set map from technosquare.

 

No. I was suggesting that he gets nitrous before the flash.

 

Not necessary. He can just ask them to leave the stock ignition timing maps in place in anticipation of running nitrous later on.

 

True. But is he's paying that kind of money, wouldn't he want the whole thing done? I wouldn't pay that kind of money just so they can raise the rev limiter and set a baseline AFR. Perhaps another kind of tune would be better suited than TS (they usually are anyway).

 

My point is that your initial statement made no sense. It doesn't matter if he installs his nitrous setup before or after getting the TS reflash, as long as he tells them he will be running it (meaning they won't mess with timing).

I agree that the TS reflash is far from the most optimal way of tuning since it's non adjustable, but that wasn't your point a few minutes ago, it was that he should install the nitrous kit before getting the TS reflash. Either way he does it, considering the word "nitrous" is used when he sends them the ECU, they won't advance ignition timing.

IMO the TS reflash only a viable tuning option for a N/A vehicle that is finished with mods, and can run a VAFC or SAFC to go with it. Not someone who is looking to run power adders, since they'll need more tuning options.

 

If the AFR is thrown off from the SSIM then yes he can.

The rev limit is only an issue to solve the top-end, however you want a Technosquare reflash no matter what if you want to get the most out of the midrange. The SSIM probably throws off AFR, but the reason you lose so much power in the midrange is that the cam timing is no longer optimized.

Hence why you need TS, so you can get the Z33 VTC maps. This with an SSIM will help area under the curve A LOT. Now, if you want to 're-tune' your car with the SSIM, just revert your AFC back to factory settings (ie; zero corrections across the board) and go from there.

Whether it makes the car run leaner or richer is really up in the air. A lot of cars with headers run lean in open loop but Maximas aren't the case, so it's really hard to tell with breathing mods on a specific engine.

Either way, it's a pretty simple mod and air is still entering the engine at 1 bar of pressure at WOT so there's no chance of damaging anything from a lean condition.

Call TS and make them raise your rev limit and get the Z33VTCs, if you want nitrous then they won't adjust your ignition curve. Can you piggyback a UTEC off of a TS modded ECU? You should. If you wanna buy both and hook one to the other so your UTEC can run your timing, you can switch maps so one for N/A and one for Nitrous?

EDIT: I read the above posts and RRodriques and Sparks have very good points. If you think nitrous is gonna be the biggest step then just get the UTEC and be done with it. SSIM + Nitrous is a good combination anyways. If you're staying N/A and looking for the simplest plug/play option TS ECU+Z33 VTCs will take care of it.

 

Make sure you get a ported/portmatched LIM along with the SSIM. Your midrange will thank you.

 

+1 on this. It's different for me, since the Kinetix ports aren't the same shape as the stock LIM ports, but I gained HUGE on midrange when I port matched my LIM.

 

During my initial comment, I assumed he would get the full flash and nothing else. I had no idea that one would even consider otherwise.
