diablo predator timing

[jaykruger]

Does any one know where I can find exactly what all the Diablo Tune does as for timming advance fuel curve ect. I have been looking all morning and can't seem to find it.

Are you taking about the "canned" predator tunes?


I think the only way to know for sure (without the revolution software), is to install the tune and datalog the spark parameters.


FYI those tunes are notoriously BAD... I would trust em.

Why are they bad?

I thought they ran pretty safe canned tunes with only minor adjustments for CAI, Catback, and 93 octane fuel.

They are usually very agressive with their timing and air fuel ratios.... which have lead to numerous engine failures in the past. Even if it was "safe" it would not be dialed in for your combo. Custom tunes are the ONLY way to go, IMO.

The reason I ask is that I have almost the exact same setup that was run in the MMFF cobra tuning article about a year back. They ended up with 88 rwhp and 130 wrtq gains with the mods I have and the prdator tune, they did complain that it was rich at the high rpm but it was a "safe" tune. I am going to be getting mine Dynoed this week to make sure nothing is supper off, but was looking for what they "Diablo" has changed vs the stock tune.

I am going to get the cable for the data logging but with the weather who knows when I can actually take the car out this week.

As for being a bad "canned" tune where have you seen this? (kinda concerned now) I looked for a while to see if anyone had problems with the pulley tune from them and only found people with complaints on Corvette forums.

As for mail order tunes any opinions on Mile-hi vs Amazon?

To be honest I haven't seen any issues with the canned tunes recently, but I saw enough bad stuff about them on SVTP back in 04 to convince me to never use em.

As far as mail order tunes... i wouldn't give $.01 to Scamazon Racing... they are crooks.

RWTD (if you are patient) and Mile HI are excellent choices though.

Mile HI seems to ret some pretty excellent reviews over @ svtperformance as well probally go with him.

If all you have is a catback and CAI, do you think a canned Predator tune would be OK?

Definitely do NOT use a canned tune if you have a pulley. I bet that's where some of the engine failures came from.

I wouldn't use one under any circumstances... but thats just me.
