Help Reading Dyno Results...

[aido]

Ah good point

[A.J]

Mate you've honestly got nothing to worry about, some of us did huge amounts of milage with the supercharger fitted, I got thru 30 or 40k and it never skipped a beat, well apart from when the belt needed changing.

As standard you don't need to worry, they'll run and run and run :D

It's not going to blow up - TTE made this to very strict standards which is how they achieved TUV certification :)

It could just be the dyno you've used has slightly low figures, some dynos give higher readings, there are loads of factors, you could take it somewhere else tomorrow and get over 200 - one point to bear in mind is that it's very warm at the moment so it's not getting that much cold air - dyno again in six months and it could be 204 :)

Just thought as well, did Steve and co reset your normal ECU when this was fitted? Don't know if he does it as standard?

Even if you don't need to do it now I used to notice a difference doing it every few months or so, just pop out the ETCS and EFI fuses from the engine bay fuse box for a couple of minutes and then replace and voila :D

Hi mate,

Wasn’t really worried about the safety of the standard TTE setup (esp. not about it blowing up! lol)- definitely feels like a good kit, was more wondering if it could be safely improved on with an engine management system - and what the benefits might be

And as for the dyno results ;was just checking if my car is different from the norm ie fuelling not too different from other peoples ect- as I thought that the power results wouldn’t vary much from the TTE figures, hadn’t really considered margin of error in the dyno and temp differences ect… makes sense though.

Gord, dont be 100% positive what you are saying is correct......

i have spoken with TTE about this a few times and they say that with the TTE kit the injectors are on the max limit - and they were not trying to sell me anything!

where did u get the information that the injectors are NOT at the max limit???

without needing to read the whole topic......yep, rob is correct, this is also the same infomation i have had direct from TTE..due to duty cycle, not there physical flow characturistics.and if you look through my posts over the years regarding this i have stated it before, hence why TTE never recomended the pulley upgrade on std cars......

So what you are saying is that the standard injectors are running at max then on a standard car.

As the s/c kit, in no way controls the air/fuel mix, its still using the same duty cycle that the standard ecu telling it to yes

All the s/c kit is doing is putting more air into the mix.

Now if you add pig/back ecu, then this can control the air/fuel better, as has been done on the turbo cars.

were not talking about piggyback ecu, you have even said it yourself, the supercharger does not control fueling all it does is ADD more air........exactly, hence running lean.

the ecu runs the ijectors at the cycle its programmed to do, no more, hence why TTE who designed the kit, also say the injectors are running at there max duty cycle with the supercharger.

remember TTE were never allowed to alter any factory settings, the supercharger had to be a plug and play option, the only addition allowed was a voltage clamp on manifold pressure....

Matt you last statment is the hole point.

From factory no car maker is going to have injectors running at max.

The is200 is running lean when you add s/c kit, yes is will, but the injectors are still running at factory settings, thats why.

So all i am saying is, if you add ecu to control the air/fuel, you will get more air/fuel from the standard injectors, you dont need to add bigger injectors upto 250bhp, just like has been done with the turbo cars

If you do that the injectors and the injector drivers are operating outside of their design parameters with regard to performance and reliability so it is to be avoided wherever possible.
