i would hope for some help/insight from a fellow rotor head.this pile of $hit went 10.80 on a $hit tune up.i am on E85.i was at the Adams track Tuesday night talking to a fc owner asking about his tune up on good gas.he said he was at 28 degrees advance at 8000 rpm on 15 pounds of boost if i remember rightmy question is what do you think about the advance i have in my tune up at 15 pounds running E85?i am at 42 degrees under vacuum over 3000 rpm.my turbo is coming on at 4000 rpm so i will start from 4000 rpm to 8000 rpm.at 5 psi @4000 rpm i am at 30 degrees and at 8000 rpm i am 37;at 10 psi 4000 rpm i am at 25 degrees and at 8000rpm i am at32 degrees;at 15 psi at 4000 rpm i am at 23 degrees and at 8000 rpm i am at 29 degrees.this car starts to nose over a little at 6500.could my timing be a little retarded?my egt after the turbo is at 1450-1500.i found number 1 rotor running lean last week and added fuel.i now have two egt gauges one for each rotor .they will be installed tomorrow.should have i broke the engine with this kind of timing?

 

I am no expert but it seems your EGT's are a little low for ethanol. Also, don't forget the split has a lot to do with it. You can run more timing with a greater split (but that may not be necessary). I would say pull a little timing out and see if your MPH goes up, thats safer than adding timing. I have been told to max the timing, start at a conservative number and advance it till your MPH starts to drop off. Then back it down two degrees and you're there. What split are you running? Also, what are your IATs?

 

thank you 13B-RX3.i am running a flat 10 degrees across the board."what are your IATs?"sorry i am no good with acronyms/abbreviations,i do not know what IAT stands for?my ecu is a haltech E8,

 

There are a lot of variables that determine the correct amount of timing to run. I wouldn't try to run "X" degrees of timing just because someone else does. Just a few of the variables are.

Fuel
Compression ratio
IAT "intake air temperature
Split
A/F ratio
Boost
Plug heat range
Type of port (port timing/VE)

The list goes on but you get the idea. The only way to find what your motor wants is by testing. Like i said, just start conservative and creep up on it. I wouldn't advise any less than 10 degrees of split though.

 

when i data logged my intake air temp it was about 80 out side and the charge air temp was 105
Fuel e85
Compression ratio fd 9.0 to 1
IAT "intake air temperature 105
Split 10 degrees
A/F ratio lambda was about high 70's
Boost 15 psi
Plug heat range ngk 11.5
Type of port (port timing/VE) stock fd port
I wouldn't advise any less than 10 degrees of split though.
lim is xs after market.upper intake is a stock fd gutted of all the stock crap.you are right just getting a little frustrated,test and tune, more track time,i just want a 9.90 pass.

 

How about cranking the boost up to 20psi for the 9.90 pass

 

it is coming,i just want to make a clean 15 psi pass.i should go 10.50 on 15 psi.the 10.80 pass @ 15 psi it spun the right tire, went a 1.44 60 ft and started to nose over at 500-600 ft.

 

What do the ground straps on the plugs look like? Do you have any good close up pictures?

 

Chris, just like Allen recommended. I would take the timing down to 24-25 degrees and make a pass and see what it does and slowly add 1-2 degrees until you get max hp or mph. Although I have never tuned with E85, your timing sounds really high for a turbo car, but maybe that is ok with E85. Also, when your car noses over, what does your A/f's look like at that moment?

 

sounds like you need more fuel and less timing ,egt's are to high for a turbo car .(example) allmotor on methanol 1400 exhaust tempeture is right there for peak horse power, but ready to lean ) )my car with 42 psi at 9000rpm reads 1000 or 1100 exhaust tempetures.I would say your egt's should'nt go above 1100 or 1200 exhaust temp . Run 20 to 30deg from vacumm to boost and from boost on only 15deg to 10psi and 10deg at peak boost and add 5% more fuel on the boost side over all.( this is very safe tune) if you have a base map.
the car noses over at 600ft( your leaning out) thats why your egt's are high , under load you need more fuel . pm me and I'll give you my #
Rene has a dyno bro come on down !!

 

Just rev it up like rotorholic does.................and if it sounds good thatS it,LOL.IF it makes boost,even better.

 

sounds good chato!!

jose back in the day video hahahaa

once you rev it up like 5 times till the limiter can't handle,dont forget to check the rear or the front iron LOL, ssssssssssi bato.......

 

rev it up with hood pup open , pull on the throttle cable traaaaaaaa11mil the gordo special !! chato sounds good

 

(RRRRRR....CCCchhhhhhhhhhhhhhhhiiiiiiiiiiiiiiiiiin nnnnnnnnnnnnnnnnnnnngggggaaaaaaaaaaaaaazzzzzzzzzuu uuuuuuuuuuuu)-
This is revving the rotary in spanish at 11K plus LOL plus dont stand near the fire wall line ,that is your safety for flywheel coming out you you know what happens

 

by now you got apex seals and other precious metals making their exit out the motor. sounds good chatto

 

don't need to check my irons its an fd

 

u might need a good tuning from Oly Machhinne Schopp...Conyo!!

 

do you have the readings from your 10.80 run ? lambda and egt's

 

I got the magic ear, You still have the front steel scatter shield crackation master Hey that guy is tuning like me on youtube

 

all you need is the magic squirt oil bottle to start the engine and keep hitting that rev limiter
