Thread: NismoTronicSA Tuning Packages

Yup, or make one. I am OBD2 32 bit, my only option was to make one. Next time I will just crimp the OBD1 ECU plug onto the wiring harness directly though.



Well once you go to the NISTune's order page it's not gets a lot clearer. I too though that you could have a real time ECU for just $240 until today, because I didn't now you had to buy a software license.

Now little more on COM ports, NISTune uses Consult connector, so you need a Consult to USB adapter ($95 from their website). While NEMU uses a USB (and does now non-supported Calum RT), they both also use COM ports. But that's how any external device like that will work. NismoTronic does make it very seamless though, by auto detecting and connecting to the NEMU COM port .




It's a more then that

You don't have to re-pin the harness connector?




AND their readily available!

reading the specs and features I'm thinking this would work well with an ITB (no plenum) setup where you would not have a MAF or MAP. Am i right? I have a friend doing an ITB VE mainly for the cool factor but he does not want to deal with running a stand alone.

With the new firmware you will be able to set it up however you want. You can have the fuel/ignition map load scale be by TPS, MAF or MAP.. it is up to you on how you would like to set it up.

sorry im not super up on my engine management. for what im talking about it would be by the TPS, is this far less accurate or efficient than having the ecu read actual air flow or density?

My friend is switching from MAF to MAP and told me he is going to use the stock MAF with the entire setup that he'll need (injectors, boost, timing, fuel etc.), log everything and then use the MAF readouts for his MAP, I imagine you could do something similar with individual throttle bodies?

It isn't near as precise, but it is rather difficult to rig up a MAF sensor to a set of ITBs and on a MAP sensor it goes to atmospheric with very little throttle.

The easiest way I have tuned ITBs was to tap each runner and run a vacuum line from each runner to a decent sized vacuum log. The attach a MAP sensor to the vacuum log.

Then setup two fuel/ignition maps. The first would be based by MAP sensor load and would be used to tune light throttle and right off idle response.

The secondary set of maps would be TPS based and would be used for WOT and heavier load conditions. You would switch to the secondary map based on pressure and TPS load. Basically you would switch to this map when the MAP sensor read right around atmoshperic (say 850-900 mBar).

Programmer's know best

Nope, but you can't even use the same plugs. OBD2 16 bit and OBD2 32 bit (B15 and P11) use two different plugs. Thus you have to crimp in the new connector or make a step down.

smart guy, that sounds like a very good way to manage ITBs. thanks for the input.
