Rob Herrod is responsible for all of the engine development. Best ask him

May want to direct that question towards Rob in Herrods forum itself.

Re: Wheres Boss Edit?

Hi Rob, valve springs, and making the Boss strong enough to rev 6300 rpm what else is needed...

Re: Wheres Boss Edit?

So basically the SCT edit is worth approx 23 rwkw and 40nm of torque through the mid range!
Thats it? with the allowance of idle and rpm limit to be changed.
This is the approx gain given from the Unichip im currently running, but i will try the SCT Edit if its gets out before the 25th october, Somehow i dont have to much confidence in that happening.

Re: Wheres Boss Edit?

hi Mick, you make a good point what power gains are made without raising the rev limiter ?
as not everyone is going to upgrade there engine to safely rev over the limit of 5850rpm.
street tuner did you guys do any tests without raising the rev limiter, if so what were the gains?

Re: Wheres Boss Edit?

Will this tune get rid of that rough idle and surging on cold start ups?? Today the idle felt as lumpy as my xygt.

which part of this post is so difficult to comprehend the timing or the fuel

Just keep your uni chip then.. If you havent worked out the rest of what it can do by reading the prior posts theres no point going over it again

This is something we spent considerable time on. Dev remapped all of the idle control paramters, changed the commanded idle from 480 - 500rpm up to 650rpm, and changed the initial airflow rate on crank. I remember Devs face when he saw the factory parameters, like 'What tha?', and then went about fixing it. Transformed the car, as you would expect.

All you need to do is look at the dyno graph again, and draw a vertical line up from 6000rpm where the original program rev cuts. You will see the power is nearly identical at 282 - 283rwkw.

However.....theres a fair chance you MIGHT come back with 'Oh, but the rev limit is 5850 in a BA GT. What deception are you showing us on the dyno with a stock rev cut slightly over 6000rpm for a factory car?'

I will answer it now, just so you dont need to ask if you feel the need.......Although the commanded soft cut - or ETC rev cut - in the program is at 5800rpm, the throttle isnt always quick enough to catch the revving engine, which is why Ford also have a hard cut built in with a hysterisis some 200 - 300rpm above the ETC cut. What happens is the factory computer tries the ETC cut at 5800, if the engine continues to rev - or its truth table determines the ETC cannont control the revs at 5800 - the PCM drops cylinders until the throttle can control the engine speed once more via the ETC...which is why sometimes you get the impression that there are different rev limiters for different gears. The actual 'dead cut' of the rev limiter all depends on the rate of crankshaft acceleration...and deceleration

Its amazing what you can find out and control once you are in the program!
