Mi16 Rolling Road

Recommended Posts

Guest SeanT

OK so went to the rolling road but it wasnt quite what I thought, it was an older rolling road who had no facility to plug into my ECU but he gave it a quick go on the rollers....it came out 160 at the fly but he reckons it was running lean and you could adjust the fuelling by putting FSE fuel valve on it, it proved this by nipping the return fuel line which upped the fuel pressure and the bhp jumped 10bhp!!!...

 

Being very untechnial on these matters is it worth my buying the FSE and going back for it to be setup or go to a rolling road who can do it all through the ECU??

 

 

Thanks guys

did you get a print out ? if so put it up here so we can see. If you read the threads on here you would never trust what he says when he quotes @fly figures. Where was it ? I'd get the AFM retracted before FSE, but I had both done and got good results (more low down though)

Firstly there isn't anything that can be 'plugged into' the Mi16 ECU so your not missing out there... 160bhp @ the fly isn't too bad to be fair, I'd be surprised if just raising the fuel pressure would give you 10bhp but there we go :(

 

As Sean mentions, having the AFM re-tracked can work well and I've heard others rate the FSE on the 205 (8v and 16v) so if you've the ££ to spend give it a go, but as the ECU isn't mappable it's kind of fit and see what it does, you can't make any other adjustments on the car.

 

Oh, are you running the full Mi16 ECU setup or the 8v ECU with dizzy adapter?

Oh well that answers that then, i thought i was missing out, so how is the timing adjusted on my car???...im running the full mi16 ecu setup.....

 

the afm retrack is the thing you can do yourself by opening the box and moving the needle slightly???...i guess if my car needs more fuel then a FSE will help then....

 

Thanks Sean

It's all done with mirrors. Did any rabbits jump out of his hat? Clean your injectors first. Mi16's are usually on the rich side.

Surely you have to be suspect about an increase in 10hp from a mixture change? It just seems very odd to me. There's normally enough fuel in the std. maps to end up with 180hp @ 12.9:1, after a cam change and few other mods. A standard Mi16 normally runs in the low 12's, high 11's. The excess fuel being used to make the extra 20hp. So it just puzzles me how you have 160hp and running lean, then instantly pull another 10hp by richening it up. Are you sure the dyno operator didn't wind the load on late to get an abnormal torque reaction?

Peter,

 

Im really not sure, this all a little above my head all i know is the reading was 160 and he mentioned there was no way of adjusting the fuel without an FSE of some type and like I say he nipped the return pipe to build more pressure and the bhp went up....if this doesnt make sense to you guys maybe I should go get a second opinion from a differnet rolling road before paying out for the FSE....

 

Can anyone recommend any decent RR near to essex??

 

Thanks again for the advce

If it is running lean then increasing the fuel pressure will just mask the symptoms not cure the fault.

 

The first thing to do is send your injectors off to be cleaned and tested. you could buy a second hand set and send them off so you can still use the car in the meantime, 1.9 8v injectors are the same as Mi16 ones.

 

ok I've just seen:

 

Oh yeah and the injectors were cleaned a few weeks ago and all flowing as they should...

 

As you know your injectors are working as they should the next thing to do is to actually measure the fuel pressure at the rail, if it is 3.0 bar all is well, if its not then replace the regulator with a known working standard part (1.6, 1.9 8v and Mi16 regs are all the same).

 

Once thats all sorted if its still running lean then the next thing to look at is the air flow meter.

 

the afm retrack is the thing you can do yourself by opening the box and moving the needle slightly???.

 

thats not possible on the 16v afm unfortunately, its the 8v afm that people retrack by adjusting the sweep position.
