interesting, thanks for the detailed response. Eventually I will have the eflex sensor tuned to run 98/e85 mix.

have already done this at 7000 haha I feel that the neighbours were less than impressed.

My goal here is to enjoy fiddling with my car while learning /practicing my tuning. I'm not fussed on outright numbers, I'm just having fun, and being a test mule if anyone has any ideas.

I'm not too fussed Tbh, with the 2540s it's never going to do much under 4500rpm. My understanding is that with rpm after peak torque you increase timing gradually to make up for loss of cylinder pressure. So with the old setup, HKS GTSS twins, it made 312awkw @21psi unknown timing. Bp98 Swapped for 2540s added e70 eflex, didn't touch ignition but added 30% fuel trim. Dumped at 17.5psi @14* 305rwkw So what I might do is bump boost up to 21psi again, 14* and go from there. Seeing as I only have my 3inch cat back on there for now I'll cap it at 21psi and add a degree or two and see how it goes.

I noticed that the e85 actually coughs and splutters when it is too lean as opposed to 98 detonating/melting itself. It's really great stuff.

Yeah I am not so worried about blowing it up, I have done a bit of road tuning before, I was just curious as we know every engine is different. And the Ford 6s I have been tuning are most likely different in the amount of advance they like. Evos seem to like up to 10degrees less than the rbs according to the maps I have seen I also set up my anti lag launch control (2step) the haltech seems pretty user friendly.

You are probably on the money there mate. Cheers

Excellent! Exactly what I'm looking for! Thank you Methz.

I understand that it isn't particularly as safe as with all the correct gear. I'm only asking to see others maps or thoughts on my timing vs boost. I'll get the ball rolling My base map 17.5psi 14* at full load. My xr6turbo 21psi@10degees timing. I don't plan on blaming anyone for blowing it up haha

I do but it's going in with the new exhaust. I ran it up on the dyno to check AFRs. .80lmda or 11.7:1 pretty steady on boost. The car made 312awkw on hks GTSS twins @21psi before the 2540s went on. So I figure I'll adjust slowly to 21psi and play with timing then while watching the knock levels. When I'm happy with it I'll dial it back a degree and leave it there. I was just curious to see what others are ballpark running.

I'm not looking to extract every last kw out of the car, just interested in seeing how my ign map compares to others with similar setups. Being told that 20degrees with 21 psi blew your ring lands and sent egts over the moon is kind of what I'm after. I was browsing the EVO e85 threads and a surprising amount of people are road tuning and sharing maps. Obviously every engine is different but I and I'm sure others who enjoy fiddling would enjoy seeing others maps.

Did some cas trigger angle pickup trickery with the haltech to get the cas to read the same as the ecu, 17.5psi @14degrees timing 305rwkw with good AFRs. Recirc issue gone, car drives great. Time to add some timing and boost. How much, I'm not sure? http://www.sau.com.au/forums/topic/452568-rb26-e-flex-ignition-vs-boost/ Thank you for the assistance

Hi there, I recently finished rebuilding my rb26. I am looking for insight into how much I can advance my ignition map with my recent swap to eflex fuel. Currently sitting at 17.5psi and 14* this made 305rwkw which to me seems like there is much more to be made. If anybody has been road tuning I'd love to see what your maps look like. I'm just looking to fiddle myself now that I have the AFRs correct. I am new to RBs but 14degrees@18psi seems mild to me. Would 22psi be more likely to see around the 14degree mark? Provided I have reasonable knock levels. Setup inc Built rb26 8.5:1 Hks 264s Hks 2540s 33gtr Fmic Full 3inch exhaust. (3.5inch ready to go on) Hard pipes +all supporting fuel sys for eflex. (Haltech plat pro reads 61% ethanol content. Any ign maps for 98 or e85 would be great if you are happy to share. Cheers Blake.

R34 GT-Four with rb26 Forged pistons Billet n1 pump. Hks 2540s Xforce split dumps- hks twin 6mm mid pipe into 3inch exhaust. Hks 264s 8.7mm with adj gears 1deg adv Stock gtr intake/airbox Hard pipe kit. Z32 afms Haltech pro. Just running in it on .8lmbda on boost with 14degrees @17.5 psi 305rwkw untuned. Turned it up to 22psi. Haven't dynod it yet. Should go near 380-400kw once I tune it on e85

I set the timing via the cas to about 20degrees using the timing light. The car was very sluggish to free rev until I added timing correction +15deg now its perfect. I will take it for a spin tonight and check timing under boost. I swapped to e85 today aswell for added safety and adjusted then fuel trim up 30% seems to run fine. I am a little worried about excessive igntion timing but at the same time its the only way the car will run. also I was thinking my vernier cam gear that is advanced 2degrees would alter my CAS output? Thus reading more advanced with the timing light than it truly is?

Ahh okay. Ill grab light tomorrow. Considering it was running fine before the battery died while it was running I will hope that Its the CAS.. or I am a spastic

Removing that advance cause it to revert to stalling. Even with bas timing showing 20degrees

Unugged the A/C compressor. Battery problem solved. Base timing on the haltech shows 24-28deg at idle but i had to add 20degrees advance so it will run normally. Total advance reads around 50deg while base timing sits at 20. I think my CAS is dodgy? 50deg advance seems excessive but the cars runs like its only at 20deg or so. I guess i need a timing light.
