diablosport tune

[Blackdeth]

ok guys i ran a search and haven't found what im looking for so here goes. I own a 04 GT and just ran the diablosport tune and now i am getting a sound like sand through the exhaust and not sure if that is the sound of detonation or is normal or just the sound of the exhaust? any help would be great. fyi this is under wot not during normal acceleration

what octane gas are you cuurently running? and did you modify the tune ?

Thats weird man. I installed mine today and it quieted my exhaust down a little

Installed a diablo tune on my '01 Cobra and it mad it meaner. Sounds great, no sand. If you pull the plugs, you can read them to tell if your getting detonation. Look for something that looks like black pepper on the porcelain insulator. You must look at all 8 to be sure.

And if there's black pepper, would that mean the engine is running rich? or lean?

not safe

The "canned" diablosport tune is not what I would call safe. It's made to be able to produce horsepower even on stock unmodded cars. Well, how does it do that? It increases timing and leans out the fuel mixture to make more power.

Now if you have a CAI and a freeflowing exhaust you have already leaned out the AF so now you are even more lean after loading the "canned" tune.

Do yourself a favor and contact www.injectedracing.com or http://www.diablosporttuning.com/forums/ (Used to be RWTD) or some other tuner, pony up the $75 or so bucks and have a custom tune emailed to you. They will have to download your cars stock tune from the ECU in your car, you email that to them along with a list of your mods, they tweak it (as per your instructions) and they email it back.

You load it in your car and there you have it...A custom tune that you know is safe because its based off of your mods.

Run the "canned" tune if you like, but you are rolling the dice imo.

i am running 93 octane and what is left of the 87 that was in the tank just under half a tank i also retarded the timing 10 degrees and am still getting it and not just under wot anymore i do believe it is the exhaust now not detonation but ive been wrong before

I ran the Diablo tune for 2 years with the timing advanced to the max on 94 octane and never ran into any problems.

This was running many 1/4 mile runs. The fact that you have a strange sound comming from your car after the tune, I would be careful though.

I just bought a tune from Doug at http://www.bamachips.com/ who is known for great tunes and great service. I haven't run the new tune at the track yet so I can't give an opinion on it.

A great place to get answers for the Diablo is at http://www.modularfords.com/forums/diablo-sport/

The guys from Diablosport answer pretty quickly. Give it a try.

Good luck.

i'd let the gas run through all the way b/c you really shouldn't run 87 on a tune for 93. after about 2 tanks of 93 you should be good to go. as with everyone else, call and see about getting a custom tune done by RWTD. they can send you a custom tune for the mods that you have done to your car and then your car would be running meaner as well as safer

I have full intake mods and full exhaust with Longtubes, whole 9 yards and maxed my timing running 93 Octane for over 2 years. No problems. Then got a dyno tune for $200. It actually felt weaker to me, could be in my head, but definately not better. The "canned" tune with my mods was not dangerously lean.
As far as your noise concern, can you run the car and get under and check the exhaust for slight leaks. Any other info about your issues would be helpful also.
