Syvecs Forums

ok so after sorting out all the little issue I have had I have been able to get it on the dyno, so far it has put 623HP at all 4 on 28psi and the tuner is very impressed with the Syvecs S8

what he has found is roughly between 60-80% throttle in the higher rpm the motor has enough air flow to make ...

Hello,

any chance of getting a lift pump output with prime times etc to run in conjunction with the PWM fuel pump control on S8 please

I have played with it some more and ended up at 4khz as any more the that and the min duty gets to low, >20%, to make any difference

while sitting there playing with the idle settings I heard the main pump start to gurgle so I shut it off and turned on the out put for FP 2 though out put testing ...

Ok so I have got my setup going and it works good so far

connected to IGN 7 on TTL set at 2khz ranging from 25% up to 90% duty but I still want to do more fine tuning on this setup

wondering what other people have got their settings set at ?

or any direction I should be going with my settings ...

Michael,

I have a Weldon 2025 as my main pump, massive over kill, and as we have found out the hard way, a very very loud pump so not only do I want to slow down the flow of fuel I need to significantly reduce the noise as this is a street car

since I have mounted the surge tank under the boot ...

Pavlo,

where do I find the logs ?

I haven't got a lambda in there yet, I am going to put twin lambda sensors in but just trying to get it running for now and will do upgrades like this at a later date, I better turn off the closed loop fueling, I didn't notice it was on

the rest I will pass on ...

Pavlo,

ok in to 7, do I need to change IGN to 1..7TTL ?

I have had custom switching unit made for this specific purpose that only goes one way, we decided a H bridge was not needed for this as the motor only needs to go one way and we could build a stronger more durable unit at the same size, I'll ...

I believe the question marks come up when you change something that might effect something else so it reminds you to check other things that the change may have effected, so for teeth setup if you have changed it from lets say 36 teeth to 35 teeth you would need to go and reset the tooth gaps so ...

ok so I am setting up the pump speed control, at the moment I have Fuel pump 1 out put switching two relays, one for lift pump and one for main pump, can I just reassign Fuel Pump 1 to FP 2 and have it turn on the relays then run a new wire to the switching unit with the PWM signal and connect it to ...

yeah I have already got it so I will just tap into the signal, I have it connected to pin 8 IN16, it's the straight through GM sensor and as best as I can find it's 50hz-150hz

I still haven't got it to idle for more then 15+/- seconds ( I haven't actually timed it ), it comes down to 1000rpm for 15 ...
