Here's a quick look at why you should consider picking your fabrication shops with some care - especially critical safety item like roll cages !! It's not the bits you can see that are the problems http://www.motorsports-group-sucks.com/ He's lucky that he never crashed at high speed, as I suspect s...

Yes, your totally right. It becomes a big air pump - much like a decel fuel cut off. Where the main problem is that many cheaper aftermarket systems have very poor strategies and a small recovery window, like simply cutting off half the injectors. When the injectors come on again, the fuel delivery ...

And I'll bet the Rotor's were using microtech's... They cut half the injectors off on their 1st step of rev limiting - which is a bad thing, the solution is only to use the hard cut (cuts all injectors) - but to be expected of those 'finest quality ecu's'. They are that bad that there is no injector...

No, that shouldn't be the case -with either style limiter you'd be thrown about. Have you set your RPM CUT RESUME (&3FE9) to smooth things out ? Prob not.......! Remember there's RPM HARD, SOFT & RESUME Speed Cut :- The value in decimal is multiplied by 2. So ..... stock - &F0 x 2 (240d ...

It turns on the rev limiter.

There has never has (or ever will be) an OEM Nissan ECU that uses ignition cut to control power!!!!

That sounds plausable - because as you change the K constant, the active point on the map moves further left.

I haven't tested it on a CA18 ecu - I'd need to set up my test rig for that.. We'll see how my time goes over the rest of the week..

VL Speed limiter is located at 3FA5 if anyone cares..


Stu

Water Temp is &3FD5, as is its set to 40'c
TP changeover is at &3FDB , currently 60h (96d)

Be careful with these as they are very powerful scalers.

Hi All, I'm looking for an old laptop enabled Microtech to do some 'testing' with. It does not need to work as I want to pull it to bits and see if there is any way to improve the injector voltage table - if there is one at all. These things are renowned for poor injector control (when fans turn on ...

Here's a bit more detailed info for you to think about.. Is there a possible way to cut spark instead of fuel at rev limit threw Nistune? Another thing would it be possible to convert maf to map sensor some how threw Nistune? thanks Cant see the mention of RACE cars in the original posting.... :) Th...

So are we talking about idle, transition or full power ??? An important point to know. Changing the timing can directly change AFR using Oxygen (wide or narrow band) sampling mixture evaluation devices. Oxygen sampling devices NEVER give the full story !!! Sorry, Peston your wrong. Bachig24u your sp...

Why are people SO badly wanting spark cut ??? Don't you realize that it can cause - 1. Cat Converter damage 2. Turbocharger damage from backfiring 3. Excessive emmisions In 20+yrs tuning, I've NEVER seen an OEM system use spark cut limiting on a turbo car - with almost none using it on NA vehicles.....

Changeover is based on RPM, TP & coolant temp Coolant temperature was an important input to determine batch or simultaneous mode too. I had to run the ECU in batch mode for compatibility with the LPG system (imagine the problems when a multipoint LPG setup monitors Injector duty for load determi...

I'm sure that we could purchase them in bulk before DSE turns fully into another Hervey Norman. Perhaps Jaycar or Altronics could be an alternative

Hi All. I've been heavily decompiling a VLT computer lately and identified a few causes and fixes. If there are ineffective earths on the vehicle you may run into troubles. Check the EFI wiring to engine and engine to chassis. Induced noise can cause frequent drop outs (RF interference). If NisTune ...
