Tuned my first car today (yes my own).

rough spec is hks to4r single turbo kit with 50mm racing wastgate 0.84 a/r housing, large street port, ported uim & lim, b&m ignition amp, apexi fuel pump, 2 additional injectors welded to uim, hks additional injector controller, hks evc boost controller, apexi ecu + datalogit etc etc, ran out of time so need to go back for another session conservative timing, and fueling 16 psi boost. It was a good learning experience for me.

dyno is in rwhp.

Sweet!!!

Thanks,



by the looks of the graph my torque really suffered at around 4,800rpm as

I was tunning 10.3:1 afr up till the end of the torque band. I guess maybe looking at things now I was a bit too cautious. At around 6,500 end of peak torque afr was back up to 11:1 to top end. Do you think there is any more torque to be released by leaning out the fuel from being so rich in the above stated rev range ??

Where is the image? Its not displayed.

Nevermind, had to switch browsers.

It's displayed on my first post. It's 55k file so if your on dialup it may take a few secs longer to display.



rgds

nice! did you get that timing thing sorted?

hmmm i thought you are supposed to get bigger numbers than that for a to4r

Well I have been led to understand that this is normal so I went with the timing that map watch showed. Therefore looking at my actual ign leading map it would a seem I am running very conservative timing but i've been told that mapwatch will be more accurate so until I can dig up more info into this it will stay the same.

I have cable modem, it just didn't load the pic the first time I opened the thread. I see it now thanks. https://www.nopistons.com/forums/pub...DIR#>/wink.png

You can, to4r can make 430rwhp at 17psi. he just hasn't tunned it there yet. He did say that it was his first try. https://www.nopistons.com/forums/pub...DIR#>/wink.png Also he is using a smaller a/r. Not the big 1.00

Maybe but I have a small a/r housing of .84

also it's my first time mapping a car so i'm sure an experienced tuner could of got

more than I did but I guess we all got to start somewhere and learn from there.

Main thing is the engine is still in one piece so it still lives to be mapped another day.



rgds

i was just curious....



pretty damn good job for first time tuning https://www.nopistons.com/forums/pub...DIR#>/wink.png

Sweet, 386 sounds neck snapping.

Sounds like you have it pretty close to dialed in, with the .84 A/R.

that it does, however he dynoed 368 you dyslexic bastard

Alot of thanks to you guy's I don't post much on here

but am on here alot reading and studying all the great information.

Basically it's from the post on this forum that gave me the knowledge to tune.

Cheers https://www.nopistons.com/forums/pub...#>/biggrin.png

I wasted a lot of valuable time on the rollers as the boost controller was playing.

Had to keep backing off the throttle due to huge boost issues. like 18psi and still climbing at only 5,000 rpm The graph was then showing 310 rwhp at only 5,000 rpm managed to sort the controller out a bit. but main issue is the controller shows one thing on the settings but it boost way over that in reality.

I had the timing really retarded to start with so luckily the 18psi boost didn't hurt.



rgds

Now that just hurts my feelings. https://www.nopistons.com/forums/pub..._DIR#>/sad.png



Apologize

What boost controller was giving you these problems?

It depends on what conservative timing is to you.



Map Watch versus actual: there are factors that retard the timing. Your logs should show real close to actual unless you're someplace really cold or hot.



FWIW...nothing:

Always run race gas when playing with timing on the dyno. It's cheap insurance.

Since you have a hundred or samples at the current boost and timing (you do, right?) then why not tweak timing up a "small" amount. Since we don't know where you are at now, take that with a grain of salt. The timing might make some more torque up high, and maybe more than leaning out the mixture. How and when you make the change are important. Let's assume you advance after torque peak too. I always liked a flat toque curve with a really early peak. https://www.nopistons.com/forums/pub...IR#>/boink.gif

mmmmmm conservative timing to me is like a flat 11 deg advance on p18 row.



I have a single turbo car here built and mapped by Rmagic with hks to4r 1.15 a/r

pfc. I will go on map watch tomorrow and see if that car is the same where map watch shows higher timing figures than the actual timing map.



I will take pics and post my ign map with comparison to a datalog of map watcher tomorrow also..





rgds

Sorry the boost controller is a hks evc I think version 4

Log everything. Save the logs.

I'm running a similar setup, with a couple of exceptions in electronics..



I got 438RWHP@1.1 Bar... (i dont have the dyno sheet handy, but vosko's seen it)

so the power is there!!

Is that 438rwhp on a dyno jet ? As I am told they always read higher ??

Is that with 0.84 a/r housing also ?? I know there is more power available but

but I don't see my setup hiting 438rwhp I wish thoguh lol.

Ok I will log everything and will post later.

cheers guy's.

don't remember? i'll have to go look around for the graph and yes .84, the one it comes with.. i have a 1.15 Split but i don't know if i want to put it on yet

added you to http://www.catenet.net/dyno.php



Let me know via PM if any info is wrong... https://www.nopistons.com/forums/pub...IR#>/smile.png

Due typical British weather yesterday it was a bit difficult trying to get logs done. The logs I did save have come out in a strange format I should just taken a picture. On monitor window my datalogit shows max boost as 0.97 consistantly.

On map watcher I have not checked the whole map buty certainly under rows p17 -18 it shows the timing 2 or 3 degrees more advanced than what I have set.

I hooked up the datalogit to the rmagic single turbo car and this showed the same thing. Both these engines have less than 5,000 miles on them.

Anyway here's my map for my car



LEAD

TRAIL

SPLIT

Sorry for the qaulity you might need to blow them up a bit.



rgds

why dont you do a screen shot using print scrn button? may be a little easier to read. https://www.nopistons.com/forums/pub...IR#>/smile.png

I been advised by a few people in the U.S that the dyno dynamics reads 10-15% lower than the dynojets most of you guy's use in the U.S.

10% ON 368 IS 405RWHP 15% IS 423RWHP dynojet number so I guess it's pretty in dynojet figures for a .84 a/r https://www.nopistons.com/forums/pub...DIR#>/wink.png



rgds

The to4r don't come with a 0./84 a/r housing as standard my one was changed from a 0.96 the standard options of a to4r is the 0.81 0.96 and the 1.15.

I had a rmagic tuned to4r 1.15 a/r the other week there was literally nothing below 5,000 rpm. I took a customer out on a test drive and in 2nd gear at 2,000 rpm I planted my right foot down we counted to five second before the turbo began to flex it's muscles.

I went to a drag competition last weekend I blew my gearbox my diff and a driveshaft https://www.nopistons.com/forums/pub..._DIR#>/sad.png

I replaced the driveshaft and diff at the event I had spares, I then tried to run it with a sick gearbox and just made the thing worse. I now have a loud rattling in each gear and no longer have a 3rd gear. I will replace the gearbox and sell it I now have just purchased it's replacement hks t51r kai on an ported engine built by knightsports & has knightsports vmount setup. When it arrives I think I will ditch ecu and boost controller add an apexi ecu another boost ocntroller bigger injectors water or alcohal injection etc etc as I want to try and run 25psi engine only has 13,000 miles since rebuild but I may be tempted to get Judge Ito to weave his magic and build me one to suit 25psi and serious amount of horsepower https://www.nopistons.com/forums/pub...#>/biggrin.png



rgds

Sorry to hear your rotten luck. I guess it is to be expected through.

Yeah that was 2nd diff in a month. I was pretty peeeddd at the time

but guess that's the life of drag racing you win some you lose some and you break some.

Hey maybe I can be the UK vosko https://www.nopistons.com/forums/pub...IR#>/smile.png
