I wrote the existing XDF for LH2.4, I also had 1989 SPG and made some good tunes.
LH2.4 is fuel and idle computer only. That is easy to tune, idle is fully adaptable so you don't even need to tune that. And fuel is easy sense all injectors trigger at the same time. You can change values in the main fuel map and there is a constant for bigger injectors, there is also MAF turbo boost cut limitation that you can tune up.
I had megasquirt on my SPG with control of direct ignition cassete, after having problems I just went back to LH2.4 and vaccum distibutor, it works better and you can tune the stock stuff to support lots of power.
If you are looking for a specific tune I can offer them for you for low price then you can see what I did then you can make small adjustments. ETC...

Sure, thats why I made the XDF so people can help themselfts. One important thing on LH2.4 ecu, the lid has to be at least partialy on the ecu when running ostrich2 on it, it is there to reduce magnetic fieldsaab spg wrote:thanks revlimit
