ok,

i,ve got the del sol running but she is bogs down on throttle.
you can slowly go on throttle and it will run fine, she idles perfect.

and it will build boost but does nothing with it. she went up to 10psi
but no power, i have checked for boost leaks and i'm good there.

pulled plugs they are sooted, there is no check engine light.


i have neptune but i have lost the neptune logger sofware and it won't
download on my computer so i have no clue whats going on.

oldskoolracer

in Kansas now was tuned in Denver, had run prior to me blowing motor, has fresh rebuild
on a stock bottom end.

neptune system, ramhorn manifold ts/t4 garret turbo, 3inch open exhaust intercooled

1000cc RC low impedence injectors.

i can't think of anything else.

Do you have a wideband in the car? what are your a/f in boost ? What part of kansas did you move to? there could be a significant change in elevation and the engine could be running lean or rich

oldskoolracer

I'm in Lawrence Kansas so yes it made a large altitude. Difference. I'm very much closer to sea level
Now I did drive the car down from. Denver and only times it was an issue. Was high boost mmeaning drag racing. At the track before I did this it was my daily for quite a while. These issues have come up
from this new motor /years on jackstands. I do not have a wideband anymore. And I can't seem
to get the datalogging software to work since its all based for the RTP or demon boards. Which I do not have. I bought it many years ago. One of the first few. And hell. I never got a license. Number ron my tuner since it was dealer only tuning back then. And he put the logger on my laptop back then
The
At computer died a long time ago. Of course.

take it to a tuner before you blow this one up too. Car should have been re-tuned in Kansas.

oldskoolracer

trust me i know that i wish i could call servion and have him burn me a chip on a new map
or send it and somehow get one of those new rtp boards etc. but for now i'm trying to work

out the kinks before i take it to the tuner so he has no issues,and goe smoothly. dont want
time taken up fixing dumb stuff instead of dyno time.

thats why fixing all leaks little issues, boost leaks etc you all know the drill there.

well its all the tune so stop driving it and get it retuned, what kinks ?

oldskoolracer

The drive ability issues ate a new problem.
The car drive fine accept under high boost.

Kinks are. ******* out flooding. At first part of throttle
But gradually. On the throttle and she runs fine middle of throttle.

She is hitting boost but is not. Using. It best way to say it
I tested pressure. On system. No boost leaks but pretty
Much how it feels. She has no added power under boost.
its weird. Even under. A bad tune or stock it will boost but do possible. Damage.

yeah thats all in the tune

oldskoolracer

But these problems are a new thing I did not have these issues
Prior. And motor is stock bore stroke. Etc. Stock long block.

So what would have changed. Not tune change compression. Same as old motor
Turbo injectors. Etc. 3bar. Map. All the same.

This is what's bothering me. And given I can do everything. But tuning I don't what there time or mine if a problem needs resolution. Before proper tuning can. Be done. I will have to trailer car 60miles away And take day off work.

This might seem like a stupid question but did you re-do your timing with the new bottom end?

phaphon

you said the altitude is a big difference that's your problem . get it tuned

Its useless he isnt understanding that a retune will fix the issues he started having now that he is at lower elevation. I've said it three times already but its not sinking in

oldskoolracer

i understand tuning,BUT as a tuner you know how annoying it is to deal with issues
on a dyno. this is why i'm trying to make sure car is 100%

i have done tuning but on mostly na or low boost areas and on systems i would
set up and later have my tuner freind Servion verify sometimes spot on others some tweaking.

other then trying to get the datalogging software to work to also make sure i have
been trying to get ideas other then a system that has not changed since the motor failure.

i have already been in touch with the local tuner and am trying to get money together
to get it on the dyno.

if i had the software i would have already gone through logs and been asking some more
technical tuning questions.

just like every tuner shop owner etc would perfer not dealing with little issues, boost leaks
leaking fluid etc. a tuner should be able to put car on dyno read data and tune accordingly, i would hate to deal with things like this myself. i am definitly thankful for any info i have gotten and hope to still get. sorry dont want to be put in the catagory of
NOOB or douche bag idiot,lol.

oldskoolracer

the biggest question i'm getting at is that the tune is still there, i'm trying to figure more somewhat of mechanical or sensor issues etc. the tune good or bad is an issue but not my main problem.

the way it is going into boost but is not gaining power and is hitting as much as 10psi so far


well, guess this is almost a waste, can't get logger to work at all no chance of even getting old datalogging software to know whats going on.

Until your car is on the dyno you won't know if its the tune or not. Sounds to me thats all it is. Engine is new, **** changes, get it tuned. If you don't you are just damaging the motor during a time critical to its longevity.

I have never seen a perfect tune on the first trip anyways. They put hundreds of hours into the stock tune. It boggles my mind when people only give a tuner and hour or two and expect it to be perfect.

Exactly ! I've tuned plenty of cars and they always only want to do the first 2 hours never want to extend the time and get it spot on. Then they call me complaining when there is weather changes or idle issues or something stupid that if had more time could work on.
