Hey guys im running hondata but the year is almost over and im going to have to store my car.

When i run 10psi my EGT's start to climb to 1500 1 of 2 things.

Run less timing?

I tried more fuel but it just bucks and does not spool.

If i could i would tune my own hondata but now burner nor software.

 

lower timing a bit

 

If you richened it up a bit and that didnt work try and come down a degree or two on the timing.

ROFL 1500 degrees farenhiet?

If so your good.

If your reading celcieus walk behind your car and kiss the car good bye

 

1500 is not bad by any means, what is your knock voltage? can you monitor how much timming is being pulled when you start to see the higher egts?

 

1500 isn't too bad...what's the timing at now at full boost wot? how is the afr there too? you can pull a little bit more timing and it might help, but if you pull timing, especially if you do it for the entire boost section, you'll have to retune...it'll richen up the entire boosted area.

 

You guys arent pointing which specific measurement.

Degrees (C) Degrees (F)

I'm pretty sure hes reading fahrenheit, hes ok then.

But from what I know that close to pre ignition range.

You can also lower your EGT's by putting a bigger exhaust on. Say you're running 2.25 tube go to a full 3" & that will help lower it

1500 isn't bad. Mine was around 1550 at 12 psi.

Lowering timing will increase the temprature.

 

add fuel, increase timing = get tuned properly.

uh 1500C = 2732F. his probe would have to be inside the combustion chamber heh.

 

Hey guys well i figured it out honadata has the setting at 16deg well u haev to set it at 0 on the timing gun. well i did and the ar is alot faster lol and only goes to 1400.

 

1550 at wot 15psi, I think aluminum starts to melt at like 1800*f. I haved hit 1700*at wot for about a month without knowing because of no egt gauge then I get the egt on and see this, come to find out my timing was so far advanced I'm lucky I didn't blow my motor .

 

too bad lowering the timing will increase temps lol. whats your idle timing and total timing?

 

lowering timing increases temps like stated, You will be just fine 1500 is low, i run around 1550-1650

 

i cruise at 1300 lol...but my total timing is only 17 degrees right now

 

add alcohol injection.

 

aluminum melts at 1215 degrees. The oxidization that forms on it melts at over 3000.

hard to tell you whats up without an a/f or a timing map... lol. but like they said more fuell or more timing both lower egt's.

less timing = more energy goes out the exhaust = hotter

 

Add timing. If your only at 16degrees total then you have lots of room to add. To give you an idea, Im running 24.5 degrees total from 5 psi up to 15 psi on pump gas with no problems. My EGT's reach 900 C on hard 1-4 gear pulls.

 

im going up to 19....i just didnt understand when i made the program....oops

 

Some excellent technical information can be found here. Be sure to add to your favorites.

Yeah ive been driving the car all weekend and it pulls alot harder and is alot easyier to drive. My EGT probe is in the top of the turb after the manifold so i loose like 100 or 200 deg of heat so i would like to stay at 1400.

Thanks for the info guys
