GSXR 750 turbo

Recommended Posts

Hi!

 

Some questions :

 

My ignition is TPS based and I use Dual Ignition  (MAP/RPM) Table switchable with cond MAP>105 kPa..it works fine

My fuel map is also TPS based with 4D correction map when comes boost.

 

I'd like to make another Fuel table, which will be working till 2500rpm and will be MAP/RPM based.

Reason: TPS based map don't work very good in lower rpms.

 

Any idea how to make it??

 

Thanx in advance

Hi Andrey

We also haver used a link G4 extreme  on a GSXR 750  now a Vipec v44

set to BAP/MAP/X over , as we see a lot of altitude change between venues and wanted better barometric correction 

main tables are rpm/tps , with a 4d  removing fuel MAP based when the turbo system begins to loose effiancy above 24 psi 

ign is  RPM/MGP , currently fairly conservative , but intending to do more work on it

Hi Greg!

 

I still can not find time to check all my mapping on dyno.  My first try with ignition map was to rewrite some civic ignition map (base map included in Link software). But it seems that cars have very conservative  ign. advance. I check up with some guys from old-school suzuki forums and they share their maps. Some of them use 28* with 28psi boost in low compression engine. Any car engine will fail immediately at this settings. No one can tell me, why is this possible with motorcycle engine...only local Bulgarian Link Dealer,  who is very experience mapper, he suggested that the short stroke is main reason. I trusted this guys and slowly start to rise the advance. Now I'm running with 30' at 14psi with stock engine and pump gas.

Not too different to mine , 31 deg at 14 psi and down to 26 by 28 psi, i think there is a lot more in it but as the bike is only landspeed racing on salt  and i am more traction limited than hp,  reliability for WOT for a 90-120 seconds is more important than peak power  , and i know what you mean by time  to check, i do want to spend a lot more time esp as e85 and flex fuel look to be my next step

'ТръÑтет' мапера ми каза, че при над 10-15 градуÑа ше ми излетÑÑ‚ буталцата. Оревах Ñичко по Сузуки драг форумите и хората ми казаха 'нека твойте хора да Ñи правÑÑ‚ коли и да не занимават Ñ Ð¼Ð¾Ñ‚Ð¾Ñ€Ð¸'. Са хората има 6 Ñекундни мотори и малко по малко и вервам. Пък и мотора Ñи кара така от меÑец и не Ñе разлита.
