I have a 99 2.5 in my Ranger and a local guy burned me a chip last week, he has no experience with this engine. Does any one know what direction I can give him to fine tune this chip?
We are working with 89 octane gas, seems to ping with over 24 degrees of timing.
Thanks Dan
This is the third burn, I am hoping to be able to stay with 89 for cost reasons. I don't think my mpg or power will increase enough to warrent $.15-$.20 higher gas per gallon.
Seems to only ping at part throttle climbing hills. Wide open throttle I cannot hear it ping. He did not change any fuel trim except for leaning it some at wide open throttle due to it being pretty rich.
Power seems about the same but mpg has come up .5-1mpg
Thanks Dan
Sounds like you are running into a lean detonation. Try the higher octane for a tank or even try a blend of some e-85 or race gas maybe a gallon to a tank. e-85 I know it sounds crazy but the E-85 does have a higher octane rating, and may just get you by. its worth a try.
ghunt, here in Sioux Falls SD. 87 octane is pure gas and cost $2.26 gal. 89 octane is 10% ethanol and cost $2.19 per gal. with no decrease in mpg from 87 pure gas. Premium is only 91 octane here and cost $2.36+ it may or may not contain 10%ethanol depending on station.
This is why I want to stick with the 89. I cannot gain enough performance or mpg to offset the cost of 91 octane gas.
If we can get this thing sorted out we will experiment with E85 (85%ethanol 15% gas) that is 105 octane. But I will lose MPG, he thinks he can keep me with in 3mpg of the 89 and the cost of E85 is $1.78.
Thanks for all the help, I plan on going to his shop on Wed. this week for some more fine tuning. All sugestions are apprecieated, little info on this site to tuning thease old Pinto fours.
Dan
went back to the shop and had some more tweaking done. Ping gone and MPG is still up,better than truck has ever done. He also put his E85 tune on the chip and installed the switch to switch between stock, 89 tune and E85 tune. I want to run at least one more 89 octane tank through before trying out the E85.
uhhhh...I didnt know mazda's got the lima. I know the B2200 got a 2.2L and that Ford used mazda engines in the probes....but this is the first time Ive heard that there is a 2.3L mazda engine. Are you sure it is? by actually comparing the two, and not just by taking the guys word for it either. I want to see pics of this mazda and its engine.
I told the ricer that bought my mx6 I had swapped in a Ford engine because it was beefier and mo powerful. I had really just replaced the mazda badge on the valve cover with a Ford one.

the newer mazdas, the ones that look like the rangers, have a 4.0L ford in them. Ford and mazda shared alot of parts in the late 80s and early 90s. You could appropriately call them Fazda's and Mord's lol.
I havent seen a mazda with the 2.3L tho, I would be skeptical, and am. Ive never heard of one having a 2.3L either.

Ford makes the Mazda Ranger on the same assembly line as the Ford Ranger. The Mazda version with the 2.3, 2.5 Pinto engines are called B2300 and B2500. Matter of fact on my 1995 Mazda B2300 the only mention of Mazda any where was the sticker on the tailgate, all dataplates clearly said mfg by Ford Motor company in the USA
if u have the 1st gen 8 plug heads they are just junk u really need the later version of them they also come with the roller cam
the compression on a turbo motor is 8.1 an na is 9.1
the turbo piston is a factory forge an the na is cast .... if boosted most is 6psi to b safe
there is a lot of high performance an factory parts for the 2.3
